ZORB for Mac?

[Tom Loredo]

Hi folks-

Has anyone out there built ZORB (the object database for Zope) for
the Mac?  If not, does anyone know of any obstacles to a Mac
build of just this part of Zope?  If not, I'll give it a go.  But
if someone already knows that it relies on system calls not
available on the Mac, I'd rather not spend the time rediscovering
this for myself!

Thanks,
Tom Loredo
