[hoc-users] Problem building HOC

[Luke E. <lu...@ev...>]

I've just found HOC.  It sounds right up my street, but I'm having problems building it.

I have Snow Leopard, with the latest GHC installed (6.12.1), and the Haskell Platform as recommended.  These were installed from the pre-built installation packages (i.e. I did not build them myself). 
I have applied the necessary patch to get gcc to build 32-bit code on my 64-bit capable machine.  Regular Haskell seem to work quite happily.

When I first ran the configure stage of the HOC build/install (i.e. runhaskell Setup.hs configure), it complained that "At least the following dependencies are missing: parsec >=3.0).
Indeed, cabal showed that parsec 2.x was installed, so I managed to force 3.0.1 to be installed via cabal (cabal install 'parsec > 3' --reinstall).  Listing the cabal packages now shows 3.0.1 installed.

I expected to see the complaint about the dependency on parsec > 3 go away when I re-ran the configure step, but it did not.

I suspect there's much I have yet to learn about the way that Haskell's cabal package management works, but right now I can't get the HOC configure step to get past this issue with the parsec dependency, and I can't run the build step until I do.

Can anyone offer any clues?

Cheers
