You just need something to keep them in sync. I have a script that sets all the version and double-checks them (and does so much more as well) before I make a release to CPAN. > package Workflow; > use Workflow::VERSION; > $Workflow::VERSION = $Workflow::VERSION::VERSION; This sort of strategy caused problems with the CPANPLUS module code awhile back in that the 'cpan->r' command showed its submodules to have no version numbers. Not sure if that's all been fixed now, but it did illustrate to me that trying to set versions via a version module is not a robust scheme.
