I don't really use the MacPorts versions of GCC (nor the ones of X11)
on Mac OS X, I did on Darwin OS but don't really bother with it now...
And for those languages that are _not_ available in Xcode Tools, like
the D programming language for instance, I use external installers...

Anyway, I can see how having a gcc port with Ada would be a good thing.

I'd go with the +macada variant. MacPorts uses outside stuff like
/usr/bin/gcc and /usr/X11R6 already, so it's even not that "dirty".
If you look at the "ghc" port, you'll see that it also uses an
available binary Mac distribution in order to bootstrap itself...

And sure, it's a lot trickier than your regular standard port.
