OSX: ImportError: dynamic module does not define init function (init_semaphore)

[dbv]

On OSX 10.8.3 with 32-bit Python 2.7.5, the gevent.monkey.patch_all() statement causes the error:

Python 2.7.5 (default, May 22 2013, 11:37:55)

'1.0rc2'

Any ideas how to solve this?

This may provide clues

a. OSX 10.8.3, 64-bit Python

import gevent.monkey; gevent.monkey.patch_all() - works perfectly.

a. OSX 10.8.3, 32-bit Python (started w/ arch -i386 python)

import gevent.monkey; gevent.monkey.patch_all() - doesn't work and spews out error messages given in previous message.

Thx!
