Nope, it's a crappy build system that doesn't auto-detect anything
really. It just makes assumptions based on uname. And there seems to
be no consideration for a case where shared libs are not available.

I asked in the irc channel and got fairly courteous response until the
ppl there realized they didn't know what to. Then they started
accusing me rather than acknowledging that python's build system is
broken. (And FYI I never made this inflammatory comment to them that
the build system is broken; I just asked for help.)

Some Googling turned up Modules/Setup[.local] files, which control
which modules are compiled into the main binary. But I can't figure
out where it decides to compile the ones not listed there as .so
files. I tried hacking the .py file that controls building them, and
the python interpreter started using up 500 megs of core and nearly
crashing my system. Not sure if that was due to my hack or if it's

If I get the rest to work, I will..
