Hello, I've got ghc 7.2.2 installed. trying to install cabal-install-0.10.2 results in: Linking Setup ... Configuring Cabal-1.10.1.0... Setup: At least the following dependencies are missing: base >=4 && <3 && >=2 && <5, unix >=2.0 && <2.5 Error during cabal-install bootstrap: Configuring the Cabal package failed Do I need to be using development versions of cabal/cabal-install if I'm also going to be using newer versions of ghc ? How do I know which version of cabal are compatible with which versions of ghc without trying to install it and seeing if it works ? Thank you, Brian
