Hi all, I would like to play a little with erlang. I downloaded Haskell platform, ang ghc and ghci seems to work. Trying to install leksah, Cabal, gives me the following error. http://trac.haskell.org/haskell-platform/ticket/110 I downloaded and installed Haskell Platform from source. Did.. cabal update cabal install cabal-install cabal install gtk2hs-buildtools cabal install leksah The last command didn't finish, with this output: ************************************************************ .. ...
