These packages all use "build-depends: base >= 3 && < 5" (except for ghc-core which cheekily uses "build-depends: base < 10" --- a practise we will ban if it becomes any more popular).

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? -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
