Also is your osx ppc or x86 based or doesn't that matter?
This is a good guide:

My code runs on x86, I haven't tried compiling for PowerPC. Freepascal have separate installations for x86 and ppc. JEDI-SDL should work with both I think.

The only thing I needed to change in my source files was a reference to the "\"-path separator in filenames (which is "/" on Linux/OS X). Otherwise it compiled without changes. Even a tiny bit of assembler code that I have works because it is all intel-platforms. Of course I have used no Windows specific units in my code.
