since ssl USE explicitly require gnutls, please change the USE from ssl to gnutls Reproducible: Always
The ssl flag means "Add support for Secure Socket Layer connections" (take a look in /usr/portage/profiles/use.desc) and that's exactly what the flag means for this package. The gnutls flag is meant to be used only when a package allows you to choose between different ssl implementations - for example, a pattern you would see in many ebuilds is that USE="ssl gnutls" means using net-libs/gnutls for ssl, while USE="ssl -gnutls" would mean using dev-libs/openssl or dev-libs/nss for ssl, and USE="-ssl" would mean not using any sort of ssl library at all. The distinction between ssl flag and implementation-specific flags (USE=gnutls, USE=openssl etc.) has been discussed many times on mailing lists and other places, e.g. see http://archives.gentoo.org/gentoo-dev/msg_0101af709ca8d751b4765685007b6d39.xml
