Hello all, I'm one of those curmudgeons still working on OSX 10.5.8. Recently I finally got around to building the latest GHC and, FWIW, everything seems to have worked out fine. I did get a few failed tests in the testsuite though, and I'm curious what they mean or if they're actually cause for concern?
