If I remember well and rereading the first post of this thread, my use case was:
Products.myproject egg was listed in setup.py's install_requires and
in my buildout I had the following:
versions = versions
eggs = [...]
z3c.autoinclude == 0.2.2
and with or without z3c.autoinclude, Products.myproject was not found.
Adding Products.myproject to 'egg = ' fixed the problem.
I thought it was only necessary to specify an egg you develop in the
src directory only in the develop variable, but it seems not, you have
to specify in the egg variable too. There is maybe a thing I
misunderstand about buildout...
But still z3c.autoinclude should emit a warning when it can't find an egg.
