There are two cases:
- The upstream versionning is compatible with our versionning, or using
DISTVERSION's magic leads to a compatible PORTVERSION, use
DISTVERSION. If it is possible to use DISTVERSIONPREFIX and
DISTVERSIONSUFFIX to make it compatible, use them.
- The upstream versionning is not compatible with our versionning, and
DISTVERSION's magic does not lead to a correct PORTVERSION, then set
PORTVERSION to the equivalent of our versionning, and set DISTNAME.
It is possible to use a third variable where you store upstream's
version and use it to compute PORTVERSION and/or DISTNAME, like the
dns/bind9* ports do.
