Looking further at what's in their trunk, I see:

if test $guess = "x86_64-apple-darwin10.4.0"
 then
        export MACHINE=macintel64
fi

if test $guess = "x86_64-apple-darwin10.5.0"
 then
        export MACHINE=macintel64
fi

if test $guess = "i386-apple-darwin10.4.0"
 then
        export MACHINE=macintel
fi

Based on this, I suspect the developers are under the mistaken impression that darwin10.4.0 is OS X 10.4 and darwin10.5.0 is OS X 10.5. This is of course not the case: darwin8 is OS X 10.4, darwin9 is OS X 10.5, darwin10 is OS X 10.6 (specifically, darwin10.4.x is OS X 10.6.4 and darwin10.5.x is OSX 10.6.5), and darwin 11 is OS X 10.7.
