This is really awesome, and definitely would have made my life easier the first time I installed GHC.

It also doesn't ship with cabal-install, which is cumbersome as well, especially for new users.

Then it patches the shell scripts to use a path relative to themselves (after following symlinks) rather than hard-coding an installation location. It also patches the package.conf.d files to use ${pkgroot} relative paths.

Due to the heuristics in Mac OS X's man, this will automatically make man pages work as well. Using Xcode here also makes it produce a signed build (which I do, since I am already paying for the $99/year license).
