Stupi^H^H^H^H^HBrave souls can do so via: cd /usr/ports/sysutils/portupgrade make install clean # edit /usr/local/etc/pkgtools.conf to taste portsdb -uU pkgdb -uF portupgrade -af # # wait a very long time if you have X + KDE or X + GNOME installed # otherwise, wait a merely long time That will rebuild *everything*. It gives me the shudders, though, because there are inevitably going to be broken ports. It's a good idea to save the old packages portupgrade makes for awhile, so that you can back out a broken port to the previous known working version (when that is possible). -- Chris BeHanna Software Engineer (Remove "bogus" before responding.) behanna@bogus.zbzoom.net Turning coffee into software since 1990.
