I have done this using Macports and the QLandKarte GT source, but it took the better part of a day. It's nice to have, but not always necessary.

One of the main problems that you are encountering is that gmapibuilder was only really designed with mkgmap in mind. Other maps, with different directory structures, etc. are not very well (if at all) supported.

What I usually do is run Garmin's map convert program (a Windows program) on the Mac using Darwine. This is actually fairly easy, and you can run MapSource this way too.

I think others have explained what you have to do with gmapsupp.img files, as this is not even supported by Garmin's Windows programs.
