Cheers, I'm very glad to hear it works.  My first thought was that `t1lib` might
fix the error, as ZapfDingbats is a type-one font, however it  seems  like  that
USE-flag only applies to the in-built  D.V.I.-viewer.   I  still  can't  imagine
why Evince fails to  find  type-one  fonts  for  P.D.F.s  without  the  explicit
direction of FontConfig.

Anyway, this font-aliasing fix seems to be a fine work-around for now.
Have a nice day.

Hi Ashley,

Thank you for the hint. I unzip the "ITC Zapf Dingbats.zip" to

and created as you suggested: /etc/fonts/local.conf with the content
above and the "check-mark" is showing perfectly.

Thank you for the solution!

[gentoo-user] Courier Sub-addressing

[Ashley Dixon]

Hello,

I am attempting to set up sub-addressing on my  Courier  mail  server,  allowing
senders to directly deliver messages to a particular folder in my mailbox.   For
example, I want to provide my University with the address
`ash-academicmatt...@suugaku.co.uk` to force all their messages into the
"AcademicMatters" subdirectory.

Unfortunately,  I  can't  find  any  official  Courier  documentation  regarding
sub-addressing.  I have found [1], however I'm not sure it will apply  as  I  am
using virtual mailboxes.

When attempting to  send  e-mail  to  myself  using  sub-addressing,  my  server
complains that the address is not found in the virtual users  table,  suggesting
that it is entirely unaware of the sub-addressing notation.

Has anyone here managed to get this working ? I believe it is sometimes referred
to as "plus-addressing", however it seems that Courier uses a hyphen as  opposed
to a plus symbol (+).

Cheers,
Ashley.

Okay, that's what I'll do (tomorrow).


Well it's an iterative process with backtracking ... one package of

I'm not sure why the x86 is coming into play here and if sse2 is

I found somebody with a similar issue on the net and a response was to
use this in make.conf:

Yes, it's Bash; I mentioned Perl and GhostScript as they are dependencies of the
script.

This is a known issue with some of the  language  packages  hard-blocking  newer
versions of the base TeXLive packages, as a new  release  of  the  base  doesn't
necessarily mandate a new release of all the subsidiary  packages  [1].   For  a
number of years, I (uses TeX every  day)  just  used  the  standalone  installer
provided by TUG.org, as the blocking used to be much harder to resolve.

I don't see any pure Perl/Ghostscript utility in that thread.  There's
a bash program, but it doesn't support compression in input files.

The pdfcrop.pl included in texlive seems to work OK with compressed
input files, but the output filesize balloons up by about 6X.

This app did work beautifully with no fuss:

  https://pypi.org/project/pdfCropMargins/
  https://github.com/abarker/pdfCropMargins

I can remove the crop marks from a PDF book, and then keep as much or
little of the remaining whitespace margins as I want.  The output file
is smaller than the input file (which is sort of what you'd expect
when you're removing stuff).

Now I can uninstall TexLive until the next time I need to tweak my
résumé. :) I usually do have TexLive installed, but a while back it
was causing a blockage when trying to do an update. So I uninstalled
it in order to get on the the 'emerge -auvND world' and never got
around to re-installing it until today.

I do not think that it is stuck in the bashrc itself, but something that 
happens in the
bashrc makes the emerge python process not realizing that everything finished. 
These are
the interesting running processes after the command
`ebuild /usr/portage/net-mail/dovecot/dovecot-2.3.10.1.ebuild qmerge`
gets stuck (I cannot see any bash still running, that's why I assume that the 
bashrc itself finishes):

Yep.  It looks like pdfcrop from texlive-core will do what I want.  It
would have helped if I hadn't trasmuted "pdfcrop" to "croppdf" when I
was searching for info!

I initially just trield downloading pdfcrop.pl and running it without
texlive installed, but it relies on texpdf.

There is also [1], which is a slightly improved version of  Oberdiek's  pdfcrop.
It uses pure GhostScript and Perl to work around some of the caveats of pdfcrop,
including  preserving  interactive  content  (such  as  hyperref  links  in  TeX
documents) and allowing you to avoid emerging the huge texlive-core package  for
one small utility.

How about pdfcrop from app-text/texlive-core ?  It allows you  manually  specify
many things, although it does, inevitably, increase the file size for  documents
with many pages.

You can use the e-file command from app-portage/pfl to check  which  package  in
Portage provides a specific  file---including  binaries.   Emerge  pfl  and  run
`e-file pdfcrop`.

[gentoo-user] Command line tool to crop PDF documents?

[Grant Edwards]

I'm looking for a command-line tool to crop a multi-page PDF document.

I want to specify the crop window on the command line.

I don't want it to automagically remove all of the marginal
whitespace.

I don't want GUI where I have to draw a box.

Google has found various references to 'croppdf' which is included in
a package of texlive extra utilities on Ubuntu.  Gentoo seems have 38
different 'texlive' ebuilds.  Is there any way to tell which (if any)
contains croppdf?

He is contrasting a stage1 vs stage3 install.  Anybody who has been
around Gentoo for 15+ years is probably familiar with this but it
hasn't been something recommended in a long time or documented in the
handbook.  I believe it used to be the recommended process.

Basically a stage1 is just a tarball of a very minimal toolchain - the
very minimum set of packages needed to build everything else and a
shell/etc, but not enough to actually boot a system (no ssh, probably
no init/openrc, etc).

You then use that stage1 to rebuild itself, which becomes a stage2.
That is done to clean up any CFLAGS issues associated with whatever
built the stage1.  Then stage2 is used to essentially do an emerge -e
@system which becomes a stage3.

The problem is that you end up rebuilding gcc/glibc/python/etc
multiple times, and all this time you don't have a bootable system.
If for some reason you have to reboot/etc it can be a real pain to
resume something like this.  This is why it was deprecated - you get
the same benefit from just starting with a stage3 and just doing an
emerge -e @world, and it means you can do most of your system setup
and get your system into a state where it can be rebooted very early,
vs having a process where you do some stuff at the start, then do some
more a day later, and do a bit more a day later, and so on.  You can
do an emerge -e @world at anytime really if you want to rebuild
everything and other than the load it is pretty transparent to using
the system, and if you reboot midway you just do an emerge --resume.

You can still find stage1 tarballs, because they're still generated by
catalyst when release media is created.  The stage1/stage2/stage3
steps are done centrally by the release media team, and then users
just download the stage3 tarball.

The full process is still used in some more exotic situations, like
prefix, or maybe when getting Gentoo running on a new arch.

Getting to the trojan horse concern - I guess anything is possible,
but you're assuming that somebody would infect the stage3 but not the
stage1.  They're both generated at the same place and signed using the
same keys.  If you're concerned about downstream infection a simple
gpg check eliminates that risk, and if you're concerned about
contamination upstream from signing then you'd need to create your own
stage1 by hand from some source you consider clean.

It seems the final echo is executed, but then the function doesn't exit
for some reason. I tried rewriting it using case, which looks cleaner to
me but fails in the same way.


function post_pkg_postinst() {
set +x
case "$CATEGORY/$PN" in
"net-mail/dovecot")
/etc/init.d/dovecot status && /etc/init.d/dovecot

echo 'going to sleep'

I can confirm this. I tried your bashrc (nice idea by the way, I normally
manually run needrestart after an update) and the dovecot install
completed but then hung. The next step is to add set +x to bashrc to see
where the hang occurs.

What do you refer to by "bootstrap"?

Do you mean setup.py in the portage tree?
