The problem is that the linker has stripped out all the symbols from
your executable, apart from the ones you actually use. When Python
dlopen()s _socket.so, it tries to reference a symbol that has been
stripped. The solution is to tell your linker not to strip the
symbols. With GNU ld, for example, the option is --export-dynamic.

Cheers,

Duncan.
