New description:

 `port -vd selfupdate` on PPC Tiger, Mac OS X 10.4.11, delivers for many
 minutes reports that this or that port has all compilers unavailable or
 blacklisted. Can't this prety useless output be suppressed?

 On the other hand port lists presumingly hundreds of ports that cannot be
 built, by whatever reason. Can't this list be suppressed?

 `port outdated` lists `xorg-server-devel` although it cannot be upgraded.
 So it is not outdated, it has finished. Why is it listed and why is port
 trying to upgrade it when invoked as `port upgrade outdated` although it's
 not possible? If you can't do anything about it why do you mention it? And
 if completeness is a design goal: while not adding an extra verbose switch
 or simple `-vv`?
