[gentoo-user] updating old box: segfaults with python

[Stefan G. Weichinger]

Greetings,

yesterday I started to upgrade an older gentoo server at a customer. It
has only been updated now and then as they tend to save money and rarely
contact me ...

I recommended to at least apply the stuff mentioned in the GLSAs ... and
applied some updates today (remote, via ssh).

Today glibc failed to merge:

But it seems that this is the consequence of problems with python.
There are various versions installed:

# eselect python list
Available Python interpreters:
  [1]   python2.4
  [2]   python2.5
  [3]   python2.6
  [4]   python2.7 *
  [5]   python3.1
  [6]   python3.3


But I get segfaults (german: Speicherzugriffsfehler) for all of them:

mail ~ # python2.7
Speicherzugriffsfehler
mail ~ # python3.1
Speicherzugriffsfehler
mail ~ # python3.3
Speicherzugriffsfehler

dmesg shows lines:

This leads to not being able to emerge something :-(

What can I do? quickpkg some python-version and copy over?
(sidenote: 32bit box ...)

I would like to avoid to have to drive there so it would be great to be
able to fix that from here, via ssh.


Thanks for any help, Stefan
