[Haskell-beginners] Multiple versions

[Tom Murphy]

My god! Another ghci!

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?

Thank you
Tom
