Hi
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.
This is on Mac OS X 10.8.4 with GHC 7.6.3.
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). I know this isn't a solution for people on OSX, but thought I'd add it here for people on Linux.
