How should I proceed?
Are you using cpphs? When you use ghc to do the 'cpp'ing it adds -I/usr/lib/ghc-6.4.1/include but if Cabal is using cpphs then I suspect that it will not. You can pass -v to Cabal to get it to show you exactly what it is invoking: runhaskell Setup.lhs build -v Alternatively you can specify the /usr/lib/ghc-6.4.1/include directory in the "include-dirs" field in the .cabal file, however this is not ideal of course since that path will vary between systems and ghc versions.
