1473	zope.interface and pyasn1 dependencies have version 'unknown'	davidsarah	somebody	"In the output of {{{tahoe --version}}} and {{{tahoe --version-and-path}}}, the zope.interface and pyasn1 versions are always shown as '{{{unknown}}}'. The versions of these dependencies are also not checked against the requirement. This is because these modules have no {{{__version__}}} property (which should be reported as bugs against [https://launchpad.net/zope.interface zope.interface] and [http://sourceforge.net/tracker/?atid=605751&group_id=93839&func=browse pyasn1]).

Note that {{{pkg_resources}}} cannot be relied on to return correct version numbers; see [ticket:1258#comment:8]."	defect	closed	major	undecided	packaging	1.8.2	invalid	version zope.interface pyasn1		531662
