     Priority:  major    |  Milestone:  1.10.1
    Component:           |    Version:  1.10.0

   Resolution:           |  release
Launchpad Bug:           |
-------------------------+-------------------------------------------------
Changes (by warner):

 * keywords:  buildbot test-from-egg easy blocks-release => buildbot test-
     from-egg blocks-release
 * component:  code => packaging


Comment:

 We changed the buildbot config to run `sys.executable tahoe debug trial
 [testsuite]`. Unfortunately that runs into the bug described in #2242, in
 which a function inside `pkg_resources` is interpreting a `__requires__`
 version specification incorrectly. The symptom is:

 {{{
 ValueError: ('Missing distribution spec', '=', '=', {'thisreqstr': '='})
 }}}

 So I think we must fix #2242 first, either by fixing our zetuptoolz fork,
 or getting rid of it altogether (#2044).
