Hi folks- I am aware that Zope as a whole cannot be compiled on the Mac. But does anyone know the situation for the components used by ZODB alone? I have heard that threading was the main obstacle to a Mac compile of Zope. Does ZODB use threading? I have experience building NumPy C extensions on the Mac, so if all that is involved is identifying the appropriate modules and creating CodeWarrior projects to build them, I will attempt a Mac build of ZODB. But if anyone knows of serious obstacles, I'd rather not waste my time rediscovering them! Thanks, Tom Loredo
