I think that if you run this, you will satisfy all the dependencies:

cabal install "hjscript<0.5.0" happstack

Thank you. That worked. I had a similar problem installing the happstack-tutorial, but found that I could work around it with this:

cabal install "Crypto<4.2.1"

And this, people, is why bounded dependencies in cabal files are so desirable.

More than desirable.

Uh... actually I was a little too quick in sending my last message. I only built crypto, not the tutorial. Trying again I hit this:

$ cabal install "Crypto<4.2.1" happs-tutorial

Try $ cabal install --constraint="Crypto<4.2.1" --constraint="HJScript<0.5" happs-tutorial (use --dry-run first to see if it finds immediate problems and if it does, add more constraints until it works, the above combination gave In order, the following would be installed (use -v for more details): DebugTraceHelpers-0.12 <snip lots of packages> for me).
