It looks like you're on a Unix box. I'm pretty sure IronPython ctypes
has only ever been tested on Windows, so it could have some
platform-specific dependencies. If you could figure out what library
it's failing to load, that might help sort it out. Make sure you're
using IronPython's copy of the stdlib as well, since it may have some
modifications to make it work.
