I basically went by the descriptions from portconfigure.tcl and didn't think too much about it.

https://trac.macports.org/browser/tags/release_2_2_0-rc1/base/src/port1.0/portconfigure.tcl#L203

I can make them more specific, but I'd need a little more info, as I only have access to Mountain Lion with the latest Xcode. What do older configurations have for /usr/bin/{,g}cc?

I'll try to work that in.
