The profiling imports were in the wrong place in the InstallShield for 4.08 (now fixed). If you've been bitten and don't fancy re-downloading, then just move the contents of <root>\ghc\ghc-4.08\imports into <root>\ghc\ghc-4.08\lib\imports, and all should be fine. -- http://sc3d.org/rrt/ | wit, n. educated insolence (Aristotle)
