Under certain conditions (pkg-descr has both "http://" and "WWW: https://" substrings) portlint emits a false positive warnings. For example, security/sks:
% tail -1 pkg-descr WWW: https://bitbucket.org/skskeyserver/sks-keyserver/ % portlint FATAL: /usr/ports/security/sks/pkg-descr: contains a URL but no "WWW:"
Fix this by handling https:// urls as well as http://
