Read:

Various sections in this cover aspects of this problem which would be
relevant, even if you aren't using mod_wsgi.
It is all because MacOS X can run on different architectures. That is,
PPC and Intel, plus 32 bit and 64 bit variants of same. Your library
doesn't have required architecture for what application that is using
it is running as.
Use 'file' command on the library to work out what architectures it
does provide. You then need to recompile stuff so it also includes
other architectures that may be required.
There are some pointers in that document about how to compile for all
architectures.
