What version of mod_wsgi are you using?

What version of Python was mod_wsgi compiled against and where was it installed 
on your system?

Do you have system wide Python versions installed and if so what versions?

Anyway, I believe this may be caused by mod_wsgi being compiled for a different 
version of Python than mod_wsgi is finding at time time.

For example, if you compiled mod_wsgi against Python 2.7.2 under /usr/local, 
but you had a system wide Python installed which was only 2.7.1 and it was the 
Python shared library which was found at run time.

You should run:

ldd mod_wsgi.so

where mod_wsgi.so is the installed mod_wsgi module in Apache modules directory.

When running this LD_LIBRARY_PATH should not be set as a user environment 
variable.

If the libpythonX.Y.so found is not from the Python installation you compiled 
mod_wsgi against, you can have problems.

In this case you should do a 'make distclean' in mod_wsgi source code and 
recompile it again. This time set the LD_RUN_PATH environment variable and 
export it, which the value of it set to be the directory where the 
libpythonX.Y.so for the actual Python version you compiled mod_wsgi against is 
located.

You only need set LD_RUN_PATH when mod_wsgi is compiled as this will cause the 
directory where the correct libpythonX.Y.so is located to be embedded into the 
mod_wsgi.so. You can validate by running ldd again.
