This use of package_dir is not compatible with 'develop'.  For 
'develop' to work on a project, you may not have any non-empty keys 
in package_dir.  If you want to use develop with this project, you 
will have to alter your directory layout so that 'core' is under 
'extern', or else move the 'extern' modules out of 'extern' and up to 
the top-level directory, and update (or get rid of) package_dir accordingly.
