 I realize this would be a pretty significant change but I'd like for
 MacPorts to not depend on Xcode. Xcode now costs money, which means that
 MacPorts depends on non-free (as in beer) software. As far as I know there
 is no convenient and free developer toolchain on Mac OS X any more. The
 MacPorts project is probably in the best position of any project to
 provide that.

 (Mozilla, the project I'm most heavily involved with, would appreciate it)
