mysteriously hidden ghc-binary-0.5.0.2

[Donn Cave]

Trying to build ghc-6.12.0.20091121, from an hc bootstrap build of
ghc-6.12.0.20091010  -- i.e., first self hosted build of ghc.

I'm hung up at the point where, after building ghc-cabal, ghc-pkg,
hsc2hs etc., it tries to generate dependencies (?) for a Binary.hs
in libraries/bin-package-db.  It can't find module 'Data.Binary' -
"It is a member of the hidden package `ghc-binary-0.5.0.2'."

OK, I am not familiar with packages, except insofar as encountered
while trying to build GHC, but from "ghc-pkg list", I would not get
the impression that ghc-binary-0.5.0.2 is hidden (no parentheses.)
I get this result with either ghc-pkg, from the 20091010 build where
ghc-stage2 is, or the newly built 20091121 version.  The command line
seems to correctly have -hide-all-packages, followed eventually by
-package ghc-binary-0.5.0.2.

The command and results below.  Is this a configuration problem with
6.12.0, or is it more likely that my ghc build is defective?

Thanks!
