Does it support source checkout via SVN? The last time I've used
portdowngrade (in order to get the xzgv image viewer to the last
_usable_ version, 0.8_9, it only supported CVS).

Another good idea probably is to have /usr/ports/packages backed
up so it's possible to manually install a formerly installed port,
in case the recent version doesn't work as expected.
