The Enigmail extension, as installed by =x11-plugins/enigmail-1.9.9, complains that it does not support gnupg-1.4.21, while the ebuild does not enforce this. (This ebuild also relies on eselect pinentry, which, AFAIK, is not required on a system with gnupg-1.*.)
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=fa75f947334521b7ef673889119b4ff1cea6358a commit fa75f947334521b7ef673889119b4ff1cea6358a Author: Lars Wendler <polynomial-c@gentoo.org> AuthorDate: 2019-08-30 08:44:22 +0000 Commit: Lars Wendler <polynomial-c@gentoo.org> CommitDate: 2019-08-30 08:44:22 +0000 x11-plugins/enigmail: Removed gnupg-1.x dependency Closes: https://bugs.gentoo.org/646990 Package-Manager: Portage-2.3.73, Repoman-2.3.17 Signed-off-by: Lars Wendler <polynomial-c@gentoo.org> x11-plugins/enigmail/enigmail-2.0.12.ebuild | 12 +++++------- x11-plugins/enigmail/enigmail-2.0.8-r1.ebuild | 14 ++++++-------- x11-plugins/enigmail/enigmail-2.1.2.ebuild | 12 +++++------- x11-plugins/enigmail/enigmail-9999.ebuild | 12 +++++------- 4 files changed, 21 insertions(+), 29 deletions(-)
