I can't wait until stackage (http://www.yesodweb.com/blog/2012/11/solving-cabal-hell) is functional, hackage can be great for weeks and then on some random day have dependency problems. Looks like the github project is active https://github.com/fpco/stackage so hopefully it will be soon. In any case, I don't think the "--only-dependencies" flag works very well, so "cabal install yesod-platform" lets cabal figure out better what to install. How I got it to work is rm -r ~/.ghc ~/.cabal cabal update cabal install yesod-platform cd path/to/notmuch-web cabal install --only-dependencies yesod devel As a side note, I plan on creating some binaries and marking the first release later today. Also, if I put it on hackage it should be "cabal install notmuch-web", and then cabal seems to be better at figuring out what to do. John
