Pine (4.64-r1)has a dependnecy to uw-mailutils. Uw-mailutils blocks pine in it's ebuild. This results that pine and uw-mailutils can't be on the same system when pine depends on uw-mailutils. Reproducible: Always Steps to Reproduce: 1. emerge =mail-client/pine-4.64-r1 Actual Results: [blocks B ] <mail-client/pine-4.64-r1 (is blocking net-mail/uw-mailutils-2004g) :: You can't emerge pine. Expected Results: ... >>> Regenerating /etc/ld.so.cache... >>> Regenerating /etc/ld.so.cache... >>> Auto-cleaning packages ... >>> No outdated packages were found on your system. * GNU info directory index is up-to-date. :: To be able to emerge pine.
Notice the line: [blocks B ] <mail-client/pine-4.64-r1 (is blocking net-mail/uw-mailutils-2004g) It tells you that an installed version of pine lesser than 4.64-r1 is blocking uw-mailutils. This is most likely 4.64, which needs to be unmerged first. This is a standard way to solve blocks. See bug #105313 for reasons this block was introduced.
