Well, I ended up restructuring the source to reflect final  
installation, ie moved what was in extern into a new src folder, and  
move pubsubcore folder into src too. However, I still need to use  
package_dir:

setup(...
     packages     = [''],
     package_dir  = {'': 'src'},
     ...
)

How would you do it without package_dir?
