I wonder if you could throw some light on this? Say you just have to use the 'sub-optimal' solution and cabal install some package foo. Later it appears in the rpm list and you can yum install it. How do you now cabal uninstall foo?

I don't know if this is the "right way" but it seems to work: ghc-pkg unregister <package> rm  the contents from $HOME/.cabal/package/hackage.haskell.org/<package>

Maybe 'cab' on Hackage is the right thing to try. -- Yucheng Zhang
