I'm getting errors (see below) trying to build the tests in http://hackage.haskell.org/cgi-bin/hackage-scripts/package/mersenne-random-0... I built the package itself using ./Setup configure -f use_sse2 I thought I had an intel core duo (also see below). I think I may be missing a library but I'm not sure which one. Thanks, Dominic.
