Perhaps DFports that differ *intentionally* could make this intent
more explicit?
OVERRIDE_PORTVERSION=... or something like that. 
Additionally, I could think of warnings when
- version is overwritten
- overwritten version and version of freebsd port are the same.
(portlint, not for general users)
