How to get it ~~~~~~~~~~~~~

The easy way is to go to the web page, which should be self- explanatory:

http://www.haskell.org/ghc/

We supply binary builds in the native package format for many platforms, and the source distribution is available from the same place.

Packages will appear as they are built - if the package for your system isn't available yet, please try again later.

I'm on OSX and I currently have ghc-6.6.1 and ghc-6.8.3 (installed from a pkg). I would like to add ghc-6.10.1 to my system. I tried to do this with RC1 of 6.10, but I found that it uninstalled my ghc-6.8.3.

What will I need to do to get both 6.8.3 and 6.10.1?

Are you sure it does deinstall the 6.8 compiler? Or does it just overwrite the symbolic links in /usr/bin? To check, have a look at /Library/Frameworks/GHC.framework/Versions After installing 6.10, there should be a 608/ and a 610/ directory. This certainly happens on my Mac and I am not aware of an option to change that behaviour. And while we are at it...a BIG FAT WARNING: If you installed the 6.10.200081007 pre-release installer package, uninstall that *before* installing the 6.10.1 package. For reasons, I don't understand, the installer otherwise half removes the old package, but doesn't seem to install the new one. Can a Mac expert shed any light on that behaviour? If you tried installing 6.10.1 before reading that, just remove the partial installation you are left with, and install again. Manuel
