Created attachment 468254 [details] notmuch-0.23.7-r1.ebuild The current ebuilds don't follow the guidlines[1]. This concerns notmuch 0.23.* and 0.24. I have only attached an ebuild for 0.23. see also bug 521372 [1] https://wiki.gentoo.org/wiki/Bash/Installing_completion_files
The guidelines say where bash-completion should installed. It doesn't state that it is necessary to use newbashcomp. Bash completion file is installed in a location returned by get_bashcompdir from bash-completion-r1. I will just change dependency to !!<app-shells/bash-completion-1.9. Sphinx is required for man pages to build. Man pages are required. Even 'notmuch --help foo' and 'notmuch help foo' execs man on the manual page, so this cannot be made optional. Thanks!
I've corrected dependency in all ebuilds.
