Um. As far as I know Linux is the only Unix we've got it working under (one
of these days I'll give Solaris a try). But considering that it runs on
Windows and Mac as well ... I'd call it pretty bloody platform independent
:)

Try doing a 'ldd /usr/local/lib/python1.5/site-packages/cvisualmodule.so'
and seeing if ld is finding all of the libraries it thinks cvisualmodule.so is
linked against.

Considering that you *compiled* it, that means the linker *can* find all the
symbols. So it's probably something dumb like a library path setting or
somesuch.

I'm vaguely inclined to think that symbols looks like a python internal
symbol. Finding where it lives means doing an 'nm | grep __get_eh_context'
on *everything* cvisualmodule.so is linked against, however ... (i guess
it's not really that bad. i'll poke around and try to find it later if
you're still having trouble).
