[STUMP] stumpwm won't start on OpenBSD macppc/sbcl

Hello,

I am a happy user of stumpwm. I wanted to use it on a macppc running
OpenBSD current (the version which will become the next release), built
with sbcl 1.3.10. The same combination on OpenBSD/amd64/sbcl works,
while it doesn't work with the macppc and I don't see any reason it
won't run. Maybe X is missing some parts ? I'm not sure accelerated
graphics works...

I tried stumpwm 0.9.9 and the git code.

Please find a backtrace of the problem, if you have any clue :-)
