<command line>: cannot satisfy -package-id mtl-2.0.1.0-5b7a9cce5565d8cc8721ba4f95becf1b (use -v for more information)
However, cabal list tells me:
* mtl Synopsis: Monad classes, using functional dependencies Default available version: 2.0.1.0 Installed versions: 2.0.1.0 License: BSD3
The right version, but possibly not the right ABI hash. Also, it might be broken by some other dependency; try "ghc-pkg list" which should give you an idea about both issues. ghc is regrettably not very good about saying *why* it "cannot satisfy" a package dependency. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
