bdist_mpkg can't do this simply yet.  It's not designed as a general 
package creation tool, it's designed to do what it does and little 

As I said, by default, PackageMaker creates mpkgs that use ".." as the 
path, so you need to manually copy the packages *next to* the mpkg.  
Not inside.

If you want to put them inside, you have to edit the plist and change 
the component directory.
