True, but we used to make ports build with a previous version installed,
whenever possible. The problems are generally caused by the build process
picking up include files or libraries from LOCALBASE instead of from the
port's source directory.

I'd expect a port maintainer to check for easy fixes to such build problems.

Maybe we should add a port variable that is true if a port conflicts with
earlier versions of itself. That would indicate to port build tools like
portmaster or portupgrade that the old version should be deleted before
starting the build of the new version (and to re-install the old version
if the build of the new one fails).

E.g.:

CONFLICTS_WITH_ITSELF=	yes

I'd be willing to integrate support for such a functionality into portmaster,
if it was accepted in the ports framework.

PS: And yes, there are good reasons to keep support for tools that are
    lighter-weight than poudriere and more portable than synth in the
    ports system.
