gcc 4.6 port for OSX Lion

Ryan,

Any good reason why?

Ryan, you’re just brilliant! I hadn’t seen this report: in fact, I get the same error on Lion, and opened a radar. But I am not sure it will be duly considered (or maybe duplicate).

By the way, Portfile for llvm-devel and dragonegg (based on gcc45) are working. May I submit those?

Cheers,
Vincent
