Getting Leksah working on Mac OS X 10.5.8

I'm using Mac OS X 10.5.8. Anot开发者_开发知识库her question indicated that Leksah is the IDE of choice for Haskell development.

However, Leksah (version 0.10.0.4) requires GHC 7.0.3 (problems with 6.12.2, problems with 6.12.3). Unfortunately, the newest Haskell platform available for OS X 10.5.8 is 6.12.3.

How do I get Leksah working on my Mac? An OS upgrade is not possible. Should I just use a different IDE/text editor?

According to the latest State of Haskell survey, the most popular IDE's are vi and Emacs, both of which have Haskell-mode features and are quite usable on OS X.

That said, it's probably worthwhile to get ghc-7 anyway. Is self-compiling an option? You can install a ghc-6.12 binary, then use that to bootstrap compiling ghc-7.0.3. Once you have a working ghc-7, download the Haskell Platform Source and build that. Compiling both ghc and the full platform will take a while, but I'd expect it all should work.

This is ghc 7.0.4 for Leopard PPC: https://downloads.haskell.org/~ghc/7.0.4/krabby/ I was also able to use it to build ghc 7.6.3.
