I decided to remove everything and start again with the Haskell Platform. I am back up and running enough to make progress. -----Original Message----- From: haskell-cafe-bounces@haskell.org [mailto:haskell-cafe-bounces@haskell.org] On Behalf Of Ralph Hodgson Sent: Tuesday, June 01, 2010 4:34 PM To: daniel.is.fischer@web.de; haskell-cafe@haskell.org Subject: RE: [Haskell-cafe] Dependency issues with GHC 6.12.2 installing parsec and others Thanks Daniel, I will give it a try I just did some work on the MAC to verify that everything worked there.

You probably have a package.conf from the previous GHC still lying around. If your new GHC is in the system space, it'll probably be enough to remove all package.conf files from the user space, if your new GHC lives in user space, remove all package.conf files from the user space *except the one ghc-6.12.2 created* (that's the one containing the package ghc-6.12.2).
Having installed GHC 6.12.2, I am hitting these problems with every package I tried to install:

I wonder what to do next?
