* Go to <https://www.haskell.org/platform/mac.html> and follow the instructions. This requires Mac OS X 10.6 / Snow Leopard or later; but there is a link to an earlier version of Haskell Platform, that's built for Mac OS X 10.5 / Leopard. During the installation, you may be prompted to install "the command line developer tools"; this is a portion of what Apple bundles together with Xcode (mentioned above on this page). The installer will take care of getting these for you if you give it permission.
- <!--
- The Installer places everything in your system directories. If you'd like it instead in your user directory (easier to clean up later), you can do this after running the Installer:
-
- mkdir ~/Library/Frameworks
- cp -a /Library/Frameworks/GHC.framework ~/Library/Frameworks/
- [ -d ~/Library/Haskell ] && mv ~/Library/Haskell ~/Library/Haskell.orig
- sudo mv /Library/Haskell ~/Library/
- sudo chown -Rh $USER:staff ~/Library/Haskell
- mkdir -p ~/share/doc ~/share/man/man1
- ln -s ~/Library/Frameworks/GHC.framework/Versions/Current/usr/share/doc/ghc ~/share/doc/
- ln -s ~/Library/Frameworks/GHC.framework/Versions/Current/usr/share/man/man1/ghc.1 ~/share/man/man1/
