The linux build completed without errors, and I ended up with a torcoind in the src dirctory, so I'm assuming it worked (that is, any other potential bugs are logic errors, and wouldn't affect your problem; I didn't run it). As far as I can tell, it's either an issue with the OSX makefile somehow (unlikely, but I'm unfamiliar with makefiles) or it's an OSX-specific compiler error as AliceWonder mentioned. I don't have a mac, so I won't be able to help much in either case.
