Hi,

I tried to do some port maintenance, specifically,
updating python and its ports to 2.6.  I used
the instructions in UPDATING for portmaster:

20090608:
  AFFECTS: users of lang/python* and py-*
  AUTHOR: m...@freebsd.org

  The default version of Python has been changed from 2.5.x to 2.6.x.
...

# portmaster -o lang/python26 lang/python25

I did not retain 2.5 as the default, so I did not create
the make.conf variable entry, nor did I run the 'portupgrade -R
python' command (I deduced the portupgrade -R command was for
those who wish to retain 2.5, was that correct?).

Anyway, I ran:

# cd /usr/ports/lang/python && make upgrade-site-packages -DUSE_PORTMASTER

Aside: From memory, I saw some complaints about libtool15/22 pass by.
Must one follow the UPDATING's timeline in reverse when doing an
upgrade that might touch many files?  I.e. should I have run the
libtool/libtldl upgrade before python's?

To continue: It chugged along (while annoyingly asking me about
deleting distfiles) until it hung on a fetch (net issues).  I hit
CTRL-C and reran the above make command.  It continued and ended
after a while with a status report of quite a few update failures
with 'uninstall errors'.

These were due to pkg_delete or 'make deinstall' dumping core
on blank @pkgdep lines in various ports' +CONTENTS files.

These blank pkgdep entries weren't there before I started the
upgrade process, as evidenced by my current backup of the
/var/db/pkg database, which has no blank entries in any +CONTENTS
files.  I got a nice command line from the net somewhere:

grep -E '^@(pkgdep|name)[[:space:]]*$' /var/db/pkg/*/+CONTENTS

I don't believe hitting CTRL-C during the fetch could have
caused ALL these blank @pkgdep lines.  There were upwards
of 50 ports with this problem after running the make commands.

Is this a know problem?  I've only seen a couple of threads
and they were one-off's (i.e. one port affected only).

I restored from backup, but I'd still like to upgrade python.
Hopefully, I can achieve this without corrupting my port
databases.

Anyone have any information or comments?  Thanks a lot!

Vinny
