Sorry, but I don't understand what steps you are performing.  How do
you get ghc to "accidentally" install a second time?

After running `pacman -Rncs ghc` *everything* related to haskell
development ought to disappear.  I'd also suggest you clean out any
locally installed packages (e.g. via `cabal install`).  After that,
the very first haskell package you install, e.g. `haskell-unixutils`,
will pull in ghc as well.  In other words, there is no need to
explicitly install ghc at all.
