I reproduced the problem and created a package reproducing it. I
thought it would be hard, but it's really easy: I have a main script
and a package 'pkg' containing submodules 'a' and 'b'. 'b' does
nothing, 'a' import 'b' with 'from . import b'. the mainscript does
'from pkg import a'. Modulefinder finds both 'a' and 'b'. Modulegraph
only finds 'a'. I included a 'run.py' script in the package that runs
them both and print the report:

MODULEFINDER
