I care for and feed a slow but charming kvm s390x guest which, if allowed, tries unnecessarily and lengthily to build gettext despite USE -nls. A handful of ebuilds, one of which is bison, insist on pulling it in. So I mask gettext and tweak the ebuilds whenever a new version appears. The bison ebuild could more elegantly make conditional a build dependency that takes much longer to build than bison itself. A patch is suggested below. --- /usr/portage/sys-devel/bison/bison-3.7.ebuild 2020-07-27 08:09:07.000000000 +0000 +++ ./bison-3.7.ebuild 2020-07-28 00:10:38.941760778 +0000 @@ -24,7 +24,7 @@ DEPEND="${RDEPEND}" BDEPEND=" sys-devel/flex - >=sys-devel/gettext-0.21 + nls?

Unfortunately bison unconditionally requires libtextstyle from gettext even with USE="-nls"
Bison gracefully does not to make the dependency on libtextstyle a hard one. Error messages are still generated correctly on a monochrome terminal without it, even with --color=always. It is the ebuild that forces the dependency.
