It is not a symlink on my system, where i built python myself, but a
15KB so file. But it seems to lack lots of python symbols.

Maybe what i should do is actually make libpython.so a physical copy
of libpyton311.so before linking to it, so now on any system the
module would look to load libpython.so, which could be pointing to any
version. I'll try that next
