how to uninstall on osx

[Wilson MacGyver]

Hi,

So how do you uninstall a previous version of haskell platform on OSX?

on a machine that has both 2011.2.0.0 and 2011.2.0.1 installed for example,
if I only want to uninstall 2011.2.0.0, what is the command to do this with?

here http://www.haskell.org/haskellwiki/Mac_OS_X
says to

sudo /Library/Frameworks/GHC.framework/Tools/Uninstaller

but that directory doesn't even exist.

Thanks
