On my system, only gcc-4.0 shows up in gcc_select (though in Xcode I have a
selection of 5 different ones); how would I get others to show up in
gcc_select?

I suppose in that case, we could use "-system" (or "-builtin" or "-distrib"
or something else) as a prefix/suffix.

But I feel like it's counter-intuitive to have "python25-apple" be the
built-in/system python, and "gcc40-apple" be something installed by MacPorts
(which confused me for quite some time).  And it seems inconsistent to label
the MP's gcc's "mp-gcc40", but MP's Pythons a prefix-less "python25".

(I suppose that last paragraph was a little redundant...)
