ghci "attempting to use module ... which is not loaded" after cabal install, in source dir

with ghc-7.6.1 (but also with ghc-7.4.1):

I do "cabal install" (with no arguments) in the source dir of some package (that has no separate src/ subdir), modules are installed fine (as shown by ghc-pkg list).

Then I start ghci (still in the same dir) and load the module that I just installed. This fails with

Prelude> :m + TPDB.Data

Top level:
    attempting to use module `TPDB.Data' (./TPDB/Data.hs) which is not loaded

It works when I start ghci from any other dir.

changed weight to 5

added GHCi Tbug Trac import labels

This is the intended behaviour. GHCi notices that the module you are asking for has a source file, so you have to :load it (the source file takes precedence over the module in the package).

We could change the error message if that would help?
