At this time, Python only supports BeOS on the PowerPC platform; if you'd
like to help me port it to the x86 platform, please let me know (I only
have limited access to BeOS on an x86 system). If you'd like to lend
me an x86 laptop running BeOS to do the port, _definitely_ let me know! :-)
I'll even give it back when I'm done.

Python 1.6 will compile "out of the box" on BeOS), try this: Python 1.5.2 and later will compile "out of the box" on BeOS), try this:
1) Get the Python 1.5.1 source code from ftp.python.org.
2) Get the Python 1.5.1 diffs from my web pages
(http://www.qnx.com/~chrish/Be/software/); if you can't get them through
a web browser, send me email and I'll mail them back to you. These
diffs should also be available at ftp.python.org along with the BeOS
binary archive.
Run autoconf. If you don't have autoconf, you can get a precompiled
version from GeekGadgets (ftp://ftp.ninemoons.com/pub/geekgadgets/...).

we fail the "genuine getopt()" test; this is odd because we've got
a real live GNU getopt() in the system libs. Other packages built
using configure (such as all of the goodies in GeekGadgets) suffer
the same fate though, so it's not a Python problem.
5) Copy Modules/Setup.in to Modules/Setup. 4) Edit Modules/Setup to turn on all the modules you want built.
