What's the reasoning behind using ld64 for gccXX?

Yeah, that was a bad idea.  I'm glad it's gone.

Yeah, symlinks would be better, but still not as good as building our own copy.

It was done before I started messing with the ports.

I don't really understand your statement, so I can't really respond.  I will offer a few points which may be related to your concern:

1) The XCode compilers will continue to use their versions and won't touch what's in ${prefix} (this is because they don't use $PATH).
2) The MP compilers will use our versions of these tools.

Please let me know if that doesn't answer your concern.
