After a little drama with zlib, I managed to get cabal-install installed. I then attempted to do cabal install HAppS-Server since this is a module with a lot of dependencies, and in rapid development flux, so perenially painful for me to install. The result is that I managed to install everything up to HAppS-State, which I think is the last dependency, but then seemed to hang indefinitely in the middle of installing HAppS-Server at the end. OK, I thought, then perhaps I can do normal runghc Setup.hs after downloading and unzipping the tar from http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HAppS-Server-0.9.... However, this resulted in error thartman@thartman-laptop:~/haskellInstalls/smallInstalls/HAppS-Server-0.9.2.1>runghc Setup.hs configure ... Setup.hs: At least the following dependencies are missing: HAppS-Data >=0.9.2... Strange, because I had just installed that module via cabal-install, and I could load it in ghci with :m +HappS.Data. I then ran ghc-pkg and got this strange result that my packages were broken into two different files. Is this by design? ghc-pkg list /usr/local/lib/ghc-6.8.2/package.conf: Cabal-1.2.3.0, Cabal-1.3.11, Cabal-1.5.2, DeepArrow-0.2, .... /home/thartman/.ghc/i386-linux-6.8.2/package.conf: HAppS-Data-0.9.2.1, HAppS-IxSet-0.9.2.1, HAppS-State-0.9.2.1, I am curious if anybody else is able to install HAppS-Server using cabal install, and whether they can shed any light on the other isuses I raised.
