I have successfully installed Cabal-1.10 with GHC-6.10. Since Cabal is 
written in really plain Haskell 98, it should also work with earlier 

I did find out, why my use of flagToMaybe worked for me, but not for you: 
With my GHC-6.10 that part of code was hidden by the preprocessor. I 
think, if we use a 'case' we need neither flagToList nor flagToMaybe, 
because we can match on Flag and NoFlag constructors.
