[Distutils] --always-copy, development eggs

So, I'm trying to achieve a couple different things with workingenv, and
I'm not sure how to make it all work...
I don't want one workingenv to have unintentional links to package in
another environment. Sometimes easy_install will find a package
somewhere else on the system, which is fine, but I want it to copy it
into the workingenv. I thought the easy thing was to add
"[easy_install] always_copy = True" to distutils.cfg. And this works.
*But* always_copy doesn't work with develop eggs. So specifically
there's a problem if I want to install both distribution A and B as
editable/develop eggs, and B depends on A. I can install (via setup.py
develop) A, and then install B, but B fails with something like
error: Could not find suitable distribution for
Requirement.parse('A==0.1') (--always-copy skips system and development
Note that 'A==0.1' is something easy_install/setuptools came up with, B
only requires 'A'.
So, it seems having always_copy on really gets in the way of development
eggs. Is there another way I can avoid sharing packages without
always_copy? Or... something, I'm not sure.
