So I made a p5-email-mime-contenttype update, but I don't know how to specify in the p5-email-mime portfile the minimum version for the p5-email-mime-contenttype module.

There is no capability to specify versions in dependencies. But it is not necessary to do so. If p5-email-mime 1.926 requires p5-email-mime-contenttype >= 1.016, then we simply commit the update to the p5-email-mime-contenttype port making it 1.016 first, followed by committing the update to the p5-email-mime port. Then you can be sure that any user who has the p5-email-mime 1.926 portfile also has the p5-email-mime-contenttype 1.016 portfile, and when they try to install or upgrade p5-email-mime, its dependencies will be installed or upgraded first.
