I have one question. It looks like the recommended way to solve the
problem is to use something like:

Flag separateSYB
 Description: Data.Generics available in separate package.

[...]
   if flag(separateSYB)
      build-Depends: base >= 3 && < 4
   else
      build-Depends: base >= 4 && < 5, syb

When the user types 'cabal install pointful' (without providing
-fseparateSYB), which version of base will be the executable built
against?
