The package has been compiled with '-package-name mwutil', but for GHC 6.6 you want '-package-name mwutil-0.1'. I suspect that you might be using an old version of Cabal - it was fixed to do this in the version shipped with 6.6, but older versions might not work correctly. Recompile your setup script?
