LoadAllTargets not loading dependencies

Hello all,

I've been following along with Stephen Diehl's blog series on the ghc
api and I am using `load LoadAllTargets` on a .hs file (let's call it
Wibble.hs) and then typechecking.

All seems well until I add a second module (let's call it Wobble.hs) in
the same package and import it from Wibble.

I can see that the load has correctly calculated the dependency graph
and includes Wobble in the dependencies of Wibble. But if I try to
typecheck Wibble, then I get an error:

    Could not find module ‘Wobble’
    Use -v to see a list of the files searched for.
4 | import           Wobble
  | ^^^^^^^^^^^^^^^^^^^^^^^

I have separately compiled the package, and can see its packagedb is
listed in the .ghc.env file. What else do I need to do so that Wibble
can see Wobble?

Best regards,
