This is a good valid point and one I have been worrying about myself sometimes.

I often find myself hitting Ctrl-C at "cabal install HACKAGE" to run
"yum install ghc-DEPENDENCY-devel"
and before returning to run "cabal install" again.

It would be nice to automate this in some way - cabal-install plugins, anyone??
