If you unpacked the distribution and tried from scratch with a new prefix, it should work. You're right, I re-configured with a new prefix. (I never tried to install with the wrong prefix but only called make in the sources.) Rather than recompiling the whole sources I grabbed a new binary distribution from the dist site. So I solved my problem but it discouraged me to compile the ghc sources (again). Aren't there just a few spots to be removed to allow changing the prefix?

Excellent example. It's very hard to give good error messages for impredicative polymorphism. I've tried to improve this one a bit.

Hi Simon, Which version of the testsuite should I be using to test my builds of the release candidates?
