Comment (by davidsarah):

 Thise check is causing several failures on the buildslaves. Arguably they
 are false positives from a user's perspective (because we ''are''
 importing acceptable versions of the dependencies in these cases), even
 though they indicate that pkg_resources is deeply confused.

 I propose that we should only perform this cross-check when one of the
 version-checking options is used ({{{bin/tahoe --version}}}, {{{--version-
 and-path}}} or {{{--debug-version-and-path}}}), or when {{{setup.py
 test}}} or {{{setup.py trial}}} is used. In the latter case, it should not
 stop us running tests.
