Well, it turns out that this is possible. I used NSAddImage() and 
NSLoadSymbolFromImage(). I could only build (and load) flat namespace 
dynamic libraries though.

When building two-level libraries, certain symbols need to be resolved 
by linking to the Python executable (ex: _environ). Bundles have the 
-bundle_loader option, there doesn't seem to be anything equivalent to 
it for dynamic libraries.

[I wish Apple would lower the restriction for two-level namespaces to 
-undefined warning.]
