[Haskell-beginners] wxHaskell install errors

Hi Gregory, just been looking at your thread here 
(We seem to be having somewhat parallel problems - I am struggling with installing wxHAskell on mac osx).

I was wondering, if you give the command "wx-config --release"
What do you get ?
If it says 2.8 (which is what I get) then presumably your 'path' is still pointing to the earlier version. And this would fit with Heinrich Apfelmus's
comments ?

I am struggling to make sense of path settings, and I raised some questions in another thread/s.

In the wxHaskell installation instructions for wxWidgets 2.8  I saw this:
"We assume in this guide that the variable $wxwin points to your wxWidgets installation directory, for example: ~/dev/wxGTK-2.8.10."
It is not in a windows specific part of the instructions, though I wonder (from the name) if it is just relevant for windows (though 'win' could also
denote 'Widgets INstallation' perhaps).

Do you recognise $wxwin (and what is it set to in your case?).
I wonder if this may be implicated in the path settings for 2.9 too.

I was also very interested by your "If the libraries
    are already installed but in a non-standard location then you can use the
    flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are."

I have not got to the cabal step yet (still trying to reach some confidence I have widgets installed and configured correctly!) but it seems this
may be the (at least an) answer to the path aspect if all else fails with trying to get an auto default path working.

Cheers/ Henry
