I managed to port and run Stackless to OpenBSD for Zaurus.

WARNING: Stackless installed itselfs as a standard Python distribution, and will crush yours if no installation prefix is provided. I install mine in /usr/local/stackless to avoid this problems.

First, download and uncompress the version 2.4.3 on http://www.stackless.com

Here is a link to the files to use for patching : http://basy.free.fr/stackless_arm_zaurus.tgz

The recursive diff arm32.patch should work on any platform, with a little tweaking. The files specific to OpenBSD/Zaurus are the patch_* files.

To build for arm32 :
- apply the arm32 patch;
- ./configure=installationprefix;
- add a -D__arm32__ to the OPT and the CPPFLAGS
- make, make install

To build for OpenBSD/Zaurus
- apply the arm32 patch;
- ./configure --prefix=installationprefix
- apply the patch_* on the proper files
- make, make install

Sorry to produce post configure patches I'm not very fond/skilled in ./configure scripts.
