* update alex to 2.2 and to use the generic Cabal builder

* change default version of ghc to ghc-6.8.2
* some references to ghc-6.6 and ghc-6.6.1 are left; these are
  packages that to my knowledge don't work without ghc-6.8.2 without
  some kind of work (such as upgrading to a later version or some
  patch); I'll try to perform these remaining upgrades soon ...
