That would certainly be the preferable solution. After all, we're not
portable already: we only support Ghc 6.2, 6.4 and 6.6.
So I'd suggest you do that. If you can check the above three versions
of Ghc, that's better, but I'll be glad to commit to the *unstable*
branch even without that.

That's going to lead to trouble.
