I've run into difficulty building happy and alex using the sandbox feature of cabal-install 1.18.0.2. Installation of dependencies succeeds but both happy and alex fail with:
setup: The program happy is required but it could not be found
My workaround is to use the --only-dependencies flag, install the dependencies, and manually install the packages.
I've run into this problem myself on Linux. My solution is to install ghc, happy, alex, hlint and cabal-install from debian packages and everything else using cabal install (either with or without using sandboxes).
At a guess, both of you need to find the bin directory created *in the sandbox* and add it to $PATH while working in the sandbox. Perhaps there is some better way for cabal sandboxes to handle this automatically. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
