[Haskell-cafe] cabal problem on OS X

[Jeroen Weijers]

Hi,

For me it turned out to be some problem with MacPorts, removing
MacPorts (with all its installed ports) solved the problem regarding
ZLib. I assume that a less drastic measure would also work (only
remove selected ports or remove the ports from your path).

Regards,

Jeroen
