This is a procedure suggested by Mark Lentczner on the haskell-platform mailing list. It clears out _any_ and _all_ versions of haskell platform, so use with care. /Anders Begin forwarded message:

These installers don't attempt to uninstall prior versions, and depending on how your prior versions were installed, they may, or may not, happily co-exist with this installation. I'm interested to hear experience reports of trying these installers both systems both with and without prior Haskell setups.

You can probably erase most (all?) traces of a prior Haskell install with this procedure: sudo rm -rf /Library/Frameworks/GHC.framework sudo rm -rf /Library/Frameworks/HaskellPlatform.framework sudo rm -rf /Library/Haskell rm -rf .cabal rm -rf .ghc rm -rf ~/Library/Haskell find /usr/bin /usr/local/bin -type l | \ xargs -If sh -c '/bin/echo -n f /; readlink f' | \ egrep '//Library/(Haskell|Frameworks/(GHC|HaskellPlatform).framework)' | \ cut -f 1 -d ' ' > /tmp/hs-bin-links # review /tmp/hs-links sudo rm `cat /tmp/hs-bin-links`

This leaves the symlinks "alex", "cabal", "cabal.real", "cabal.wrap" and "happy" in "/usr/bin", and also leaves "/Library/Frameworks/HaskellPlatform.framework", and while I can remove those myself how can I be certain there isn't something else left behind?

At a terminal prompt:

sudo /Library/Frameworks/GHC.framework/Versions/Current/Tools/Uninstaller sudo rm -r /Library/Haskell

Simple question which an hour of googling and a question on #haskell couldn't satisfy. :(

I have installed the Haskell Platform 2011.2.0.0 on Mac OS X 10.6.6.

Now how do I uninstall it?
