[stuff about how somebody distributes an .egg for Twisted-Core]

This may not be helpful, but it is additional data: Twisted
subprojects are not easy_installable in any reasonable way. The only
thing that it makes sense to easy_install right now is "Twisted". This
has to do with the way easy_install attempts to install non-root
packages. Anyway, maybe it makes sense to depend on "Twisted Core"
sometimes to workaround buggy Debian cruft, but bad things will happen
if this results in easy_install ever attempting to download Twisted
Core as opposed to Twisted.
