Public bug reported:

Hello,
(Centos 5, x86_64)

Upon a code deployment this evening, apache failed to restart with this
message:

Starting httpd: httpd: Syntax error on line 55 of
/etc/httpd/conf/httpd.conf: Syntax error on line 1 of
/etc/httpd/conf.d/python31-mod_wsgi.conf: Cannot load
/etc/httpd/modules/python31-mod_wsgi.so into server:
/etc/httpd/modules/python31-mod_wsgi.so: undefined symbol:
PyUnicodeUCS2_DecodeLatin1

After some digging, I noticed that Python had been upgraded to 3.1.3
just a couple days ago (in my case, via yum-cron):

May 26 04:15:47 Updated: python31-3.1.3-2.ius.el5.x86_64
May 26 04:15:47 Updated: python31-libs-3.1.3-2.ius.el5.x86_64

I suspected that mod_wsgi was built against an outdated api/abi in
python, so using mock, I rebuilt against python 3.1.3, installed that
RPM, and everything works fine.

I've attached my SRPM which increments the release and provides a note about the error.
If anyone is in need of a temp hot-fix, the RPM can be found at: http://code.appcove.com/python31-mod_wsgi-3.3-2.ius.el5.x86_64.rpm

Thanks!
