Summary: emerge --deep --update world fails to due blocked packages Steps to Reproduce: 1. emerge the following packages: sys-apps/pam-login-3.17 sys-apps/shadow-4.0.7-r4 sys-apps/utemper-0.5.5.6 media-libs/faad2-2.0-r9 2. Real life: emerge --deep --update world Expected Results: Just normal regular system maintenance. Actual Results: # emerge -av --deep --update --tree --oneshot pam-login These are the packages that I would merge, in reverse order: Calculating dependencies ...done!

[blocks B ] <media-libs/faad2-2.0-r9 (is blocking media-libs/libmp4v2-1.4.1) [ebuild U ] media-libs/faad2-2.0-r11 [2.0-r3] +xmms 8 kB [ebuild N ] media-libs/libmp4v2-1.4.1 4,678 kB Notes: 1. pam-login-4.0.14 is the newest available stable x86. Depends on shadow >= 4.0.11-r1 and !>=4.0.14-r2 latest stable shadow is 4.0.15-r2, thus does _not_ satisfy deps. portage does not realize that shadow-4.0.14-r1 is also stable _and_ satisfies deps. WORKAROUND: emerge -av --oneshot =shadow-4.0.14-r1 echo "=sys-apps/shadow-4.0.15-r2" >> /etc/portage/package.mask This is a bug. portage simply should not try to update packages if it cannot meet deps, but _not_ block everything. 2. xterm-207 depends on virtual/utempter xterm-207-r1 depends on libutempter libutempter depends on !virtual/utempter As sys-apps/utempter is installed, xterm-207-r1 is blocked WORKAROUND: emerge --unmerge utempter emerge -av --deep --update xterm Is there a reason to depend on a specific utempter? It is a bug to block update world just because of changing deps. 3. libmp4v2-1.4.1 depends on faad2 !<2.0-r9 portage does not realize that it is about to update to faad2-2.0-r11 satisfying the dependencies. This is a bug.

just remove (emerge -C) pam-login package and make sure that shadow complied with 'pam' flag.
