I am just answering as no one else has, I don't know about Macs so don't know the exact solution, but usually this sort of error is caused by some development tool or library that is not installed or is the wrong version. If you were following a set of instructions for installing on the Mac then maybe you have missed installing something. If you weren't then possibly you can find some to follow.
