You need to link your application with -Wl,--export-dynamic.

As the first step, I recomment that you avoid using shared libraries
as extension modules. Rebuild Python, and make everything a static
module in Modules/Setup. All extension modules will then end up in
libpython22.a.

As the next step, I recommend to write a config.c (or copy the one
generated when building Python, adjusting it to your needs). Compile
config.c into your application, and you won't depend on any external
extension module.

This leaves you with the Python modules. For that, I recommend to use
freeze. Invoke freeze on your application, and it will generate a set
of C files. Compile those into your application as well. freeze will
also generate a Makefile (in a subdirectory), which you might find
useful, or which you can ignore.

HTH,
