I just upgraded from a PowerBook to a MacBook Pro. The migration

they are running via Rosetta. This also means I can't update any

have been so many posts lately about things failing to build on
10.5,
I'm a little scared to wipe my old macports system and rebuild from
scratch. I particularly can't afford to be without a LaTeX

right now.
So, is there any way I can "jail" a new installation of macports?
If I
can build everything successfully, I want to be able to delete
the old
version and move the new one to the standard location.
You can have multiple installs of MacPorts on a single system.
However, some ports may not work if you change the location of the
installation. So, I would recommend that you move the existing
installation aside (i.e. `sudo mv /opt/local /opt/ppc`) and
install a new one in its place. If you succeed at getting the new
one running sufficiently, you can get rid of the old one;
otherwise move the old one back in place.
In order to quarantine two MacPorts installations, you should
build them from source. The tarballs are available on the
Downloads [1] page. You should ./configure them along the lines of
the following:
% ./configure --prefix=/opt/local \
--with-tclpackage=/opt/local/share/macports/Tcl
You can pick something other than /opt/local if you want, but it
might not work to move it back to /opt/local later, should you
care. Also, it's possible that you might get conflicts for files
installed in /Applications/MacPorts or /Library/Frameworks.
I was concerned about configuration files outside of /opt/local. But
now that I think about it, even if there are any, the Intel port won't
have a different configuration than the PPC one. So that could
probably work. Thanks.
Configuration files go in ${prefix}/etc, so there shouldn't be any
outside of ${prefix}. However, some ports do install other things
outside of ${prefix}. For example, into /Applications/MacPorts. You
should also rename /Applications/MacPorts to /Applications/MacPorts-
ppc before installing MacPorts again, and remove it later once
everything's ok. If you had any server programs, they may also have
installed startup items in /Library/LaunchDaemons (if you were
running Tiger and up) or /Library/StartupItems (for Panther and before).
Some ports will install other things outside the prefix, perhaps in /
usr/X11R6. I'm guessing these items weren't migrated from the old
system, therefore any ports that depend on this are now broken.
You don't need to build MacPorts from source; you could also just
install from the Mac Ports 1.6.0 Leopard disk image. But before you
do, you will also need to rename /Library/Tcl/macports1.0, for
example to /Library/Tcl/macports1.0-ppc.
If your "port" command were working, "port contents foo" would show
you what a port installed. You could run "port contents installed" to
see everything installed by all ports, and filter this to see
everything that was installed outside of the prefix, for example
since your prefix is /opt/local you could run:
port contents installed | grep -v '^Port .* contains:' | grep -v /opt/
local
However, you said yourt "port" command isn't working, probably since
it needs the Tcl libraries in /Library/Tcl/macports1.0, and these are
for the wrong architecture.
If you still have this ports installation on the PowerPC Mac on which
it was originally installed, you could run the above command there,
to discover where else outside of ${prefix} items were installed, and
use that information to remove those files on the Intel Mac prior to
reinstalling MacPorts.
