I'm pretty well stumped at this point. I've cleared off everything and
gone up to GHC 6.12 HEAD, and a 'cabal install happstack-data' gives
me the same symbol not defined error in Happstack.Data.Xml.Base.

But here's the spooky part, if I run it by hand like so:

ghc --make src/Happstack/Data/Xml/Base.hs
src/Happstack/Data/Default.hs src/Happstack/Data/
DeriveAll.hs src/Happstack/Data/Normalize.hs src/Happstack/Data/Migrate.hs

after resolving issues due to CPP not being run, everything runs to
completion, no errors. Also, the list of things we're pulling in
during the template-haskell execution is much smaller (see bellow).

Has anyone seen this, where template-haskell behaves different when
run from cabal-install (or Setup.hs) than from ghc --make (or ghci)?

That was the successful build, using ghc --make. The error for te
failing build is quoted bellow.
