I have ghc in my path, have set up yesod init and cabal built it.

Now, when I 'yesod devel' I get :

cabal: Cannot find the program 'ghc' at 'yesod-ghc-wrapper' or on the path

ghc IS on the path!

thanks

I can't say I've ever seen that error message before. If no one responds on SO, it may be worth sending a question to the mailing list. – Michael Snoyman

I've seen that if the path to the yesod bin directory under cabal is not in my PATH.

Try changing your PATH to include the yesod directory and see if it goes away.

For example, in my .bash_profile I have:

export PATH=$PATH:/Users/username/Library/Haskell/ghc-7.4.2/lib/yesod-bin-1.2.2/bin/
