Pip's use of --record to record a list of installed files actually
predates uninstall too (though of course it was useful/necessary in
implementing uninstall).

Uh, maybe? What does --single-version-externally-managed have to do with
dependencies? Does it prevent the installation of dependencies? I didn't
realize that.

In that case, does pip's --egg flag (which removes
--single-version-externally-managed from the install command, but
doesn't replace it with anything else) break requirements files?
