I have always understood CONFLICTS to indicate, that some port
can not be *installed* at the same time as some of the ports listed
as conflicting.

Building such a port while a conflicting version is installed, is
possible most of the time. If such a build fails, it is most ofter
due to the build preferring the already installed headers over those
provided with the new version (i.e. a wrong ordering of include
paths).

Since port developers typically test ports in poudriere (to get a
clean build environment and e,g, to be sure, all dependencies are
correctly specified), they often don't notice such conflicts with
already installed versions of the same port.
