Hmm, I thought the docs weren't built by default.  Did you ask for the
docs to be built by setting anything in your build.mk file?

The error means that the configure script couldn't detect the right way
to process DocBook documents on your system.  Since you're on Gentoo
(right?) I can tell you that the Gentoo DocBook setup works perfectly:
just 'emerge docbook-sgml', and re-configure your GHC build (remove
config.cache first) and you should be able to build the HTML docs.  To
build the printed documentation you'll need to install more stuff (TeX &
JadeTeX at least).

Oh, and BTW you can do a 3-stage build in a single tree these days.
Just 'make bootstrap3' from the top level.

Cheers,
