 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.
