GHC, Haskell Platform installations.

So after great angst, a good night's sleep, and a day not spent thinking about it, the problems of yesterday were dispatched pretty easily today.

GHC 7.0.3 installed without a hitch. As did the Haskell Platform. "Configure, make, sudo make install" for the win.

Then, after a tweak to the cabal file, my code compiled as well. It was limiting base library versions to <= 5. Hence, it couldn't be compiled after the upgrade.

The occasional problem aside. I'm always impressed with the reliability of cabal and Haskell packaging in general. It's not perfect, of course, but once I get past my own ignorance and the occasional somewhat less than helpful error message, it works more often and with less fuss than any other code management tool I've used.
