It's not meant to be needed for building from a source tarball.

Good news: I have cured the massive code-explosion problem you encountered with
GHC 6.8. I'm about to commit a patch for that, so it'll be in GHC 6.10.
However, I'm now getting a complaint about overlapping instances (DoCon 2.11).
GHC 6.10 is being a bit more consistent about coherence.
