Local package DB doesn't take preference over global DB

I sometime find myself wanting to compile some small test program (say Test.hs) against a locally built Cabal package. Here's what I do:
ghc -c Test.hs -package-conf dist/package.conf.inplace
This doesn't work
Test.hs:4:0: Failed to load interface for `Data.Text.Lazy.Builder': Use -v to see a list of the files searched for.
The global version of text gets picked instead of the local one (and in this case the global version lacks the Data.Text.Lazy.Builder module). I expect the package given on the command line to take preference.
Workaround: Bump the version number of the local package.
