The problem is that what I currently have is the latest version of the<br>
Haskell Platform which is available as a binary for Mac OS 10.5.<br>
If I want a more recent Haskell Platform, I need to build from source<br>
(and/or use port or brew) which I haven't been able to do<br>
successfully, but I guess that's a different post....<br>
