Threads in Solaris?

[jwray at mifund.com]

I wrote a threaded app on my win2k box, not realizing that threads 
weren't part of the standard python install. Now that i want to 
install my code on a solaris box it complains that it doesn't have 
thread.py. I would copy the one from my win2k box, but it imports 
win32, which I'm sure wouldn't work out.

So my question is, where can I get a threading module for solaris? 
I've read off verious sites that one exists, but I haven't been able 
to find it for download.

Thanks!
