Comment (by michaelld@…):

 xxdiff is at 3.2, which is quite old & looks to work with Qt3 and older
 Qt4; probably won't work with the current qt4-mac.

 xxdiff 4.0 looks like it should work with current qt4-mac, but it's non-
 trivial to do the update -- some patch fixes & other changes to the
 Portfile.

 so, I think adding in a dependency on libGLU is the way to go for now --
 simple and quick!
