It doesn't appear to be mandatory in the package description, which
misled me.  What may be going on is as follows (from the CompileScript):

#!/bin/sh -ev

        if [ -x /usr/bin/gcc-4.2 ]; then
                export CC=gcc-4.2
                export CXX=g++-4.2
                export CPP=cpp-4.2
        fi
...

I.e. it uses /usr/bin/gcc-4.2 if present (new enough Xcode on 10.5, and
10.6)

If you have a /usr/bin/gcc-4.2 on your system (maybe as a symbolic link
to /sw/bin/gcc-4.2) then this could potentially derail the build.

If you don't, then that's a different matter.  But without actually
_seeing_ a config.log snippet it's hard to say what's happening here.
