[Haskell-cafe] problems using macports?

[S. Doaitse Swierstra]

I am in my yearly fightto get a working combination of operating system (Snow Leopard), compiler version (6.12) , wxWidgets and wxHaskell on my Mac . 
After deleting most of my stuff, starting afresh, hours of building using macports etc. I finally get the message:

loeki:Opgave doaitse$ ghc --make Turtle.hs
[1 of 1] Compiling Main             ( Turtle.hs, Turtle.o )
Linking Turtle ...

Some Googling showed me that the same problem has shown up with Yi,  The solution however is not there. Can someone enlighten me.
