OK. I can see that. However, I don't want to restrict haskell-devscripts to working with only one version of Cabal. It is up to the package maintainers to depend on the version of Cabal they want, and to conflict on the version they don't want. There is no code in haskell-devscripts that is putting different paths there; this must be a change in Cabal. > > So I'm not sure what I'm supposed to do here.

But removing the That would be bad; it would leave no way for people to build packages with the current Cabal version in ghc6. > libghc6-cabal-dev would be fine be me as well. OK, I think I'll do that. That makes sense. > > Also, I'm not sure that it is incorrect for build behavior to change > > with a different version of Cabal. > On itself no, but if I don't chose a specific Cabal version, the > behaviour should be consistent. I don't think there's anything I can or should do about that in haskell-devscripts, as I said. Cabal is deciding on install paths, and if applications care about specific install paths, they need to dep or conflict on specific cabal versions as appropriate. -- John -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
