Is this on an x86_64 machine? I've just now made a change to the psyco ports to indicate that they only work on i386.

Sorry about that It is a x64 machine. Python is universal variant. Would it not work?

[jmr@…]

Probably not, since psyco's build system is not picking up our arch flags.

Seems to build OK after the changes from #24802. You no doubt have to run the i386 half of a universal python in order to use psyco.
