Comment (by davidsarah):

 Replying to [comment:20 davidsarah]:
 > In [4942/ticket1306], we replace {{{require_auto_deps}}} with
 {{{check_all_requirements}}}, which compares the requirement with the
 imported version as obtained directly from each package module. Then in
 [4959/ticket1306], we change that check to use verlib and add tests for
 both verlib and {{{check_requirement}}}.

 I should also have mentioned [4949/ticket1306], which generalizes the
 check to handle disjunctive requirements like "pycrypto == 2.0.1, ==
 2.1.0, >= 2.3" (and also exposes {{{check_requirement}}} at module level
 to make it testable).
