[Haskell-beginners] wxHaskell path

[Henry Lockyer]

Hi all 
Trying to work out how to get wxHaskell correctly installed on mac os x (10.6.8 snow leopard).
Have decided to try and get the older version working (0.13) so as to use the pre-installed
wxWidgets (2.8.8 it seems).  I was looking at the wxHAskell install info for mac os x at 
(1) http://www.haskell.org/haskellwiki/WxHaskell/MacOS_X   -  which only talks about widgets 2.9,
but I have now been reading
(2) http://www.haskell.org/haskellwiki/WxHaskell/2.8 

Question: 
The variable "$wxwin" is referred to in the page at link (2) above, where it says: 
"We assume in this guide that the variable $wxwin points to your wxWidgets installation directory, for example: ~/dev/wxGTK-2.8.10."
And in the page at link (1), step 3, it says:
"Check your path to make sure you are using your wxWidgets and not the default Mac one"

Are these referring to the same thing?  ( I had originally interpreted 'path' as referring to $PATH.)

The reference to $wxwin is in instructions for building wxWidgets 2.8 which I should not need to do if I am 
using the already installed 2.8.8 widgets library, but if I echo $wxwin it is blank and does not therefore appear to
point to my wxWidgets installation directory.
Is this an issue or is it only relevant to the initial build process for wxWidgets?

Can anyone throw any light on this?

Thanks/ Henry
