Problem shown by using __rbenv:
__rbenv/nicotest
__git /home/nico/.rbenv
__package git
__directory /home/nico/.rbenv
require="__git/home/nico/.rbenv"
__git /home/nico/.rbenv/plugins/ruby-build
__package git
__directory /home/nico/.rbenv/plugins/ruby-build
1) if children do NOT automatically depend on their parents requiremnts
__directory /home/nico/.rbenv/plugins/ruby-build fails:
because __directory /home/nico/.rbenv/plugins is created by
__git /home/nico/.rbenv, but __directory /home/nico/.rbenv/plugins/ruby-build
does not depend on __git /home/nico/.rbenv
2) if children DO automatically depend on their parents requiremnts
__package git from __git /home/nico/.rbenv/plugins/ruby-build depends on __git /home/nico/.rbenv.
__git /home/nico/.rbenv depends on __package git (via autorequire)
=> circular dependency, they depend on each other
