[Haskell-cafe] haskell on OpenBSD 5.5

Good day all, I installed OpenBSD 5.5 in order to learn haskell. There are a few glitches however. I installed the haskell-platform meta-package and the issues I noticed are: - hs-vector wouldn't install - ghci wouldn't start, the message: unable to load package `integer-gmp' Has anyone experienced the same issue? Is this happening on OpenBSD 5.4? Is this OpenBSD specific? Thanks in advance.
