Hi, I'm trying to teach myself Haskell and have installed the platform on my Mac along with Leksah.

I'm trying to use cabal to get some updates (in particular mtl so that I can get the gtk library working) and cabal wants to update itself.

However, when I try to do this, I'm running into various issues

1) I get a lot of warnings about the Module Prelude being deprecated (possibly due to some legacy haskell installs?)

It's due to the new base version, but a lot of code still implicitly imports Prelude, you can safely ignore it for now.

2) The update is being installed into a different location ~/.cabal rather than to /usr/local/bin/cabal (which itself is an alias to /Library/Frameworks/HaskellPlatform.framework/bin/cabal) so no matter how many times I try to update, I keep getting told there's a new version. So how can I make the update go into the correct location?

Try $ cabal install --global cabal-install

Many thanks,
