[Eric] Segmentation fault

[Posted to ML also to be a daunting example of consequences, when mixing 
installations from tarballs with those from package management]

Looks like you trashed your installation - usually by installation of 
arbitrary tarballs, while those packages are installed by rpm.

This is the best recipe to produce such a disaster, you're looking at.

Now you know the reason, why you should _always_ install rpms and never ever 
install tarballs in a sane system. I don't. If you need to update to a 
newer version, roll your own _RPM_. Learn to build rpms, and your life's 
getting much easier under linux. While at it, be careful with rpm --nodeps 
and rpm --force. There's a strong reason, why yum doesn't provide those.

OTOH, rpm -e && rpm -Uhv is fine..

Note, that package management is one of the greatest advantages of linux 
over other OS. The computer equivalent of the difference between childhood 
and being grown-up.

Come back, when you cleaned /usr/local (basically, remove _all_ _files_ 
there), reinstalled everything below /usr/lib64/python2.6 from rpm and when 
output of rpm -Va doesn't contain any lines with 5 in the third column 
which aren't below /etc.

If you managed to provide a --prefix=/usr argument to a connfigure script, 
wipe your platter, reinstall, and follow my words in the first paragraphs.
