gdbm and bsddb are python wrappers for C libraries that aren't part of OSX, if you want to use them you have to install those C libraries manually (GNU DBM and Sleepycat DB).

Apple has a patch that enables building dl on 64-bit OSX, I haven't had time to check if that patch is actually valid.

"configure --enable-universalsdk=/ " results in a binary that is 32-bit and runs natively on i386 and ppc machines.

That should work, but only when setup.py finds that readline install.

On 10.6 the compiler generates 64-bit code by default, use:

configure --enable-universalsdk=/ ...
