Go read:

http://code.google.com/p/modwsgi/wiki/ApplicationIssues#SSL_Shared_Library_Confl
icts

and other parts of that document about possible core dumps.

It appears you have conflicts over versions of SSL library used by Apache, 
Python and maybe even mod_php.

Closing as never found to be an issue in mod_wsgi that needed addressing.
