Macport installation failed

[interferenz]

Hello,


I have tried to install Leksah via MacPorts on OSX 10.5.6 PPC, but the  
following
error occurred:

cabal install leksah
Resolving dependencies...
cabal: dependencies conflict: ghc-6.10.2 requires Cabal ==1.6.0.3  
however
Cabal-1.6.0.3 was excluded because Cabal-1.6.0.1 was selected instead
Cabal-1.6.0.3 was excluded because leksah-0.4.4.1 requires Cabal ==1.6.0

I have installed ghc 6.10.2.with sudo port -k install ghc gtk2hs hs- 
cabal, ghc 6.10.1 was already installed.

Obviously there is a version conflict, how can I solve it?
I am not a dedicated unix dude by the way...


greetings
Volker
