I managed to find, buried in the developer documentation, the meaning https://devmanual.gentoo.org/general-concepts/dependencies/ There are also shortcuts for conditional situations: Compact form Equivalent expanded form app-misc/foo[bar=] bar? ( app-misc/foo[bar] ) !bar? ( app-misc/foo[-bar] ) So, OpenSSH can be built either with or without openssl having the bindinst useflag But another package requires openssl having the bindinst useflag disabled Can we clear this up in the emerge output? Some sort of text explaination of what `useflag=` actually means Something like Note: [useflag=] specifies a conditional dependency The following packages can be built with or without the specified dependant package useflag (dev-libs/openssl-1.0.2j:0/0::gentoo, installed) pulled in by >=dev-libs/openssl-0.9.8f:0[bindist=] required by (net-misc/openssh-7.3_p1-r7:0/0::gentoo, installed) ^^^^^^^^ The following packages require the following dependant package useflag configuration (dev-libs/openssl-1.0.2j:0/0::gentoo, ebuild scheduled for merge) pulled in by >=dev-libs/openssl-0.9.8g:0[-bindist] required by (net-voip/telepathy-gabble-0.18.3:0/0::gentoo, ebuild scheduled for merge) ^^^^^^^^
The dependency syntax is complex enough that it's too much information to display on the terminal, so I think the best that we can do is refer to the Dependencies section of `man 5 ebuild`.
