From my latest world update: !!! The ebuild selected to satisfy "x11-plugins/pidgin-sipe" has unmet requirements. - x11-plugins/pidgin-sipe-1.18.0::gentoo USE="-debug -kerberos -nss -ocs2005-message-hack -openssl -telepathy -voice" The following REQUIRED_USE flag constraints are unsatisfied: exactly-one-of ( openssl nss ) Very few people will have nss or openssl in USE. REQUIRED_USE should really be a last-resort anyway. I would recommend dropping the openssl use flag, and doing this instead: RDEPEND="nss? ( dev-libs/nss ) !nss? ( dev-libs/openssl )" econf ... $(use_enable nss) $(use_enable !nss openssl)
I've dropped the NSS flag and made it the default. Thanks for the report!
