OK, I'm working on matrix stuff in Haskell now (I've been trying to get the professor to approve that) and when I use cabal install to install hmatrix, it fails at HUnit with: ----------- Configuring HUnit-1.2.2.1... Preprocessing library HUnit-1.2.2.1... Preprocessing executables for HUnit-1.2.2.1... Building HUnit-1.2.2.1...

The exception was: exit: ExitFailure 1 ---------------- Short term question: what the heck do I do with this? Long term question: how can I handle cabal failures of this type without bothering the list every time? Dave Barton University of Toronto
