Hmm, nuking ~/.cabal and ~/.ghc seems to have fixed it.
Good old cabal. When in doubt, delete everything.

Hi list,
I've got a number of modules in a project set up like this:
project |-- foo |-- bar |-- baz `-- sandbox
where 'foo', 'bar' and 'baz' are modules which depend on one another, and 'sandbox' is a sandbox. Before building from scratch, I do a $(cabal sandbox init --sandbox=../sandbox) in each of the module folders.
If I run $(cabal install ./foo ./bar ./baz) from the projects/ directory, everything is happy. However, if I reconfigure one of the sub-modules with different flags, it fails with missing dependencies:
# in foo/ $ cabal build Package has never been configured. Configuring with default flags. If this fails, please run configure manually. # module builds correctly
$ cabal configure --enable-tests Resolving dependencies... Configuring foo-0.1...
$ cabal build
dist/setup/setup.hs:13:8: Could not find module ‘System.FilePath.Glob’ Perhaps you meant System.FilePath (from filepath-1.3.0.2) System.FilePath.Posix (from filepath-1.3.0.2) Use -v to see a list of the files searched for.
Glob is installed in the sandbox.
I've tried pointing to the sandbox config file manually with both $(cabal --sandbox-config-file=project/foo/cabal.sandbox.config) and $(cabal --sandbox-config-file=project/cabal.sandbox.config) with the same result. Cabal insists that Glob isn't installed until I nuke the foo/dist directory and start over.
I figure there's some flag I need to pass to `cabal configure` that I'm missing, but I can't figure out what it is. Anybody have any hints?
Cheers, Alex
