[Haskell-cafe] [Haskell] macports, cabal, cabal-install difficulty

[Antoine Latter]

I don't know about the ld warning, but cabal-install can never know
which version of cabal-install is installed, because it doesn't track
executables - it only tracks and knows about libraries.

Right after the warning is the line:

> Installing executable(s) in /Users/matthew/.cabal/bin

So it looks like it might have worked :-)

You can either add ~/.cabal/bin to your path, or move/soft-link the
cabal-install executable to your preferred path.

Take care,
Antoine
