I tried to do "emerge depclean" and it said a package would get removed, but when running "equery depends" on that package it had dependencies. This is because depclean uses the ebuilds in /usr/portage, while equery uses the ones in /var/db/pkg, which are the ones actually installed and whose ebuild might have a version less than the one in /usr/portage. I expect both commands to have the same result.

depclean is broken. It even says that your current have an affect.

SOrry to post again, but could the problem be with the RDEPEND and DEPEND values in packages. Afterall, if _some_ packages need a lib for building, but not for running, might that affect things? Of course, in my case, pam comes up for removal as well as devfsd. These two make no sense: sys-fs/devfsd selected: 1.3.25-r8 protected: none omitted: none sys-libs/pam selected: 0.78-r2 protected: none omitted: none mars peter # equery d pam [ Searching for packages depending on pam... ] app-admin/sudo-1.6.8_p9 app-misc/mc-4.6.0-r14 dev-libs/cyrus-sasl-2.1.20-r2 kde-base/kdebase-pam-4 net-fs/samba-3.0.10 net-misc/openssh-3.9_p1-r2 net-print/cups-1.1.23-r1 sys-apps/util-linux-2.12i-r1 sys-apps/shadow-4.0.7-r3 sys-apps/pam-login-3.17 sys-process/vixie-cron-4.1-r7 x11-misc/xscreensaver-4.22-r2
emerge --depclean and equery "depends" use two different methods to determine dependencies. --depclean takes into account your current operating environment when calculating deps...try a USE="-*" emerge --depclean -p to see depclean pull out TONS of things that are dependencies. For the odd behavior of depclean, you will want to check your world file as well as any USE flag changes.
Actually...
