[Haskell-cafe] Ease of Haskell development on OS X?

[Colin Adams]

If I try this, pango fails to compile with lots of error messages
about error: macro names must be identifiers.

I think I've seen this before - some well-known Mac OSX problem? (I'm
a linux man myself - so I'm not used to the mac)
