[Haskell] Package removal

[Yang Zhang]

How do ghc users on Linux (esp. Debian/Ubuntu) systems remove
packages? AFAICT there's only cabal unregister, and no way to remove
files but manually, which is tricky when these packages are
interspersed with other files in /usr/local. I found some old mailing
list threads mentioning that this is an open issue, but as I'm
currently facing this, I'm wondering if there's been any news on this
front. Thanks.
