If pkg_resources is not available the couchdb.__init__ modules sets the version string to '?'. We shouldn't rely on pkg_resources for something so important, especially as it's the only use of pkg_resources.
Not something I've done anything with. I'm guessing it annoyed me while I
was in the middle of something so created the issue so it wouldn't get
forgotten. Clearly, that tactic failed ;). Not sure why it's assigned to me
actually, I guess that's the default for new issues.
