Thanks for the recommendation. I tried installing with homebrew, and it went fairly smoothly. Only 12 minutes to build haskell-platform, as opposed to the 11 hours to run port upgrade outdated yesterday!
I did have to get help on one thing though. Although the mac ships with libarchive.dylib, it doesn't have archive.h. In order to install that, the following steps are necessary, since the libarchive package is otherwise blacklisted:
brew tap homebrew/dupes
brew install `brew --prefix`/Library/Formula/libarchive.rb

The problem is that there are 2 incompatible versions of libiconv -- one that ships with the mac, and one that's built with macports and that many macports-compiled libraries depend on.

I hit this problem while trying to build a foreign-function interface to libarchive.
>> So I built ghc from scratch -- in fact I built the whole haskell-platform. This was relatively painless, and fixed the libiconv problem. However, it brings me to the real point of my message, which is that the version of haskell-platform available via macports is way out of date (2009.2.0.2 http://www.macports.org/ports.php?by=name&substr=haskell-platform).
>> I'm wondering whether the haskell-platform team has considered maintaining a macports version of the haskell-platform for us mac users in addition to the binary install that's available now. This would avoid the incompatibilities such as this nagging one with libiconv. Perhaps it's just a matter of maintaining template versions of the port files?
