Comment (by zooko):

 I just remembered that there is the {{{--single-version-externally-
 managed}}} flag. If you pass that flag as an argument to {{{python
 setup.py install}}} then it will suppress all automated fetching of
 dependencies. We test the use of this flag on all of our buildbots--look
 at the buildsteps called "install-to-prefix", e.g. [http://tahoe-
 lafs.org/buildbot/builders/MM%20netbsd5%20i386%20warp/builds/116/steps
 /install-to-prefix this one on NetBSD] and "test-from-prefixdir", e.g.
 [http://tahoe-
 lafs.org/buildbot/builders/MM%20netbsd5%20i386%20warp/builds/116/steps
 /test-from-prefixdir this one on NetBSD]. "install-to-prefix" does an
 install using {{{--single-version-externally-managed}}} to suppress
 automated resolution of dependencies, and "test-from-prefixdir" runs the
 unit tests in the resulting target directory where it was installed to.

 Please try adding {{{--single-version-externally-managed}}} and see if
 that is sufficient to close this ticket.
