Comment(by adfernandes@…):

 Turns out that `cloog` checks specifically for `ppl` version 0.10.x; `ppl`
 version 0.11 will not work. I'm adding (testing right now) to add
 `--without-ppl` and `--without-cloog` to `gcc45` and `gcc46` right now,
 letting `graphite` be a variant. (I'll add a ticket when I have them
 tested.) That *should* keep things mostly independent.

 It turns out that `gcc45` with ppl and cloog requires a special version of
 cloog (cloog-ppl from the gnu repository), and that version needs polylib.
 I tried to build it; that's how I know... :-)
