Hello Simon,
I have seen several manifestations of this issue now. I filed a report
here:

Hello,
That sort of missing symbol error at link time is often (but not
always) a
sign that some libraries got recompiled but not others. So there are
references to the old symbol names hanging around.
I would try to ghc-pkg unregister syb-with-class and everything
that depends
on it, and then try cabal install happstack again.
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)?

Did you submit a ticket for this? I don't recall seeing one.
Cheers,
Simon
