When you say "they are definitely installed", what do you mean?  If
you mean you have installed Ubuntu packages like libgtk-dev (or
whatever it is called), that's good, but not enough. Cabal is looking
for *Haskell* libraries which contain the bindings to those foreign
libraries.  You will have to install gtk2hs, which provides them:
