Hey,

I followed your "Compiling python with emscripten" wiki page exactly, step-by-step. I'm 95% of the way there trying to compile Python 2.7.5. I have tried Python 2.7.4 as well and I get the exact same errors, so I suspect I'm just missing a system package or library in general. Building the _socket module seems to be failing. Did you ever come across this issue?

Stack trace from a 2.7.5 modules build:

Hmm, yeah, I think I wasn't able to get all the modules to compile. I may have just commented out the socket module. Sorry I can't be more help.
