[gentoo-user] python-2.7 update: re-emerge of cracklib failed, how can I fix it?

[Jarry <mr.jarry@gmail.com>]

Hi,
apparently I screwed something during python update, and now
I can not fix my system. This is what I did:

emerge --sync
emerge --ask --update --deep --newuse world

At the end, I have seen:
You should run 'python-updater ${options}' to rebuild Python modules.

So I did, then "emerge --depclean", and that was my mistake:
python2.6 has been unmerged before I switched to python2.7.
Im just surprised python2.6 has been unmerged, when it was
still active and selected python version.

Then by revdep-rebuild I got a lot of error-messages and
at that time I realised something got wrong.

Then I switched to python2.7 (eselect python set python2.7),
and tried revdep-rebuild again. Two packages needed to be
emerged again: libxstl and cracklib. The first got emerged
without a problem, but for cracklib emerge failed with
this messages:

My question is: how can I fix this mess?
