Thanks for helping me find that.

Re-running the Haskell Platform installer ends with an "Installation Failed," and I know enough to not start swapping out binaries in /opt/local/bin, so is there a best-practices way to fix this?

If the other is in /opt/local/bin then this is probably from Macports and so you need to remove it. I had this issue and had to unintsll haskell and its varias ports so port uninstall x where x was haskell-platform, hs-platform-cabal , hs-platform-haskell-src and anyother hs* If you dion't use macports for anything then see http://guide.macports.org/#installing.macports.uninstalling -- Mark
