-------------------------------------------------+-------------------------
 The following error happens on {{{python setup.py build}}} when using
 Nevow 0.10 and zope.interface 3.6.4 (it appears to be the new version of
 zope.interface that introduces the problem, since we normally work fine
 with Nevow 0.10):

 Drew Perttula posted a workaround to
 [http://drewp.quickwitretort.com/2011/07/08/0 monkey-patch
 zope.interface], but it is difficult for Tahoe to apply this workaround
 because the failure happens in {{{setup.py build}}}, before any run-time
 Tahoe code has executed.
