[Haskell-cafe] Installation of the New Haskell Platform

[Mark Lentczner]

As Brent said, each version of GHC needs to build its own copy of the
packages you use in your projects. Conveniently, these are all kept in
separate directories by GHC version, so you can leave your old ones around
as you compile new ones with the new platform.

However...

Most users don't want multiple versions installed at once. The Mac Haskell
Platform installer, since 2011.4.0.0, installs a command uninstall-hs on
your system. You can use that command to uninstall prior versions of GHC
and the Platform. You can safely run it either before or after your
installation of 2012.2.0.0. It is a very cautious program, and you can just
safely run it on the command line - it won't remove anything until
explicitly instructed. Pay attention to it's output, including the last few
lines which will explain how to proceed with actual removal.
