I'm not sure about substacks, but if you "start using" the stack the 
external is associated with, it will be available to other scripts. I 
myself keep these stacks in separate files rather than substacks.

I don't use the distribution builder, but I've found that when you open 
the stack that has its externals property defined, the external should 
be in the current (at that instant) directory in order to be loaded. 
What I do is set the directory to the location of the external, then 
"start using" the stack associated with it. After that I can reset the 
directory as I like.
