Comment(by adfernandes@…):

 `ppl` and `cloog` (which has also been updated) are integral to the loop-
 transform and vectorizer for `gcc46`. I was just surfing the latest
 gcc-4.6.3 build instructions, and it seems we ''should'' be good to
 upgrade `ppl`, `cloog`, and make the `cloog` variant default on `gcc46`
 (or really, just remove the variant and make it a strict dependency).

 I'll build and test when I have time; this could take a while... :-)
