The build process should be only slightly different from the standard Linux one. However, the semantics are a bit different. To configure, you should use:
./configure --host=powerpc-apple-rhapsody10.0
The reason for the host setting is that OSX doesn't seem to set a 'host' environment variable like most other Unices do (don't ask me why Apple didn't do that; it seems dumb to me).
Also, instead of make, use gmake instead.
[EDIT: Remind me in the future not to use the CODE tag; that really messed things up...]
