The Gentoo awstats ebuild has a use flag for geoip, which if selected brings in the dependency of dev-perl/Geo-IP. However dev-perl/Geo-IP is being replaced by dev-perl/GeoIP2 which superseeds it. The exact same ebuild situation exists for SpamAssassin, and there is talk about how to fix the same issue in that package here: https://bugs.gentoo.org/675494 So a possibly fix might be from this part of the ebuild: geoip? ( dev-perl/Geo-IP ) to geoip? ( || ( dev-perl/GeoIP2 dev-perl/Geo-IP ) ) Or I suppose a straight requirement on only GeoIP2.
Nothing to do for perl here.
