Haddock's internal GHC version must match the configured GHC version
I'm trying to build ghc-184.108.40.20680603 with haddock-220.127.116.11, and I get the above error when the build tries to emit docs for the base package.
I'm not really sure how to make progress here. 2.0 is the default version of haddock distributed with Fedora 9. I don't know if haddock 0.8 has the same problem, but unfortunately I can't use it without tremendous bother.
Doubly unfortunately, I can't actually tell whether the error is coming from GHC, the system's Haddock, or some other place entirely.
What I'm trying to do is prepare the GHC 6.8.3 RPM for Fedora, so that we can roll it in short order once the official release is announced. I'm sorry to be so completely clueless :-(
