trove-classifiers requires calver
by lucabon from LinuxQuestions.org on (#6JJEW)
The new package "python-trove-classifiers" requires "calver" lib. It will download "calver" automatically if it does not found it, but I think it will be better to include "python-calver" as a separate package in order to have a fully-offline building.
