I’ve installed gtk2hs-buildtools with no problem, but here’s the output when I try to install gtk using ‘cabal install gtk’:

This problem occurs on both my Mac and in my Fedora VM. Does anybody know how to fix this? Thanks!

    You need to add the path in which the Gtk2Hs build tools are stored to your $PATH environment variable, so that the build process can find them. On Linux, it’s $HOME/.cabal/bin. On OS X, it’s $HOME/Library/Haskell/bin (although that might just be if you’re using the Haskell Platform — if that doesn’t work, try $HOME/.cabal/bin).

    To add a directory to your $PATH, run export PATH=directory:$PATH. You should probably add this to your shell’s startup file (it depends on your shell and OS — probably either ~/.bashrc, ~/.profile or ~/.bash_profile). (You’ll need to do so if you want to run any programs you install with cabal directly, anyway.)
