- Mute extraction commands and do not use shell wildcards if possible
- Remove IGNORE on FreeBSD versions before 900038, they're unsupported
- Do not claim that port is broken on PowerPC (builds and links fine)
- Remove custom naive `do-build' target: add missing `all' target to
supplied Makefile instead
pkg_cleanup finds packages that are not requested by any other installed
package and lets you decide for each one if you want to keep it or delete it.
It also allows viewing the pacakge comment and description.
This program is essentially a clone of pkg_rmleaves except that it shows
the comment and description of packages and does not support GUI dialog(1)
