A month ago Opera for Linux 24 was released. Unfortunately it was released only as a 64 bit deb package. Thats not a problem because an ebuild was already written (details: bug#514696). On Sabayon: Add PORTDIR_OVERLAY="${PORTDIR_OVERLAY} /usr/local/portage/" to /etc/make.conf # make an ebuild mkdir -p /usr/local/portage/www-client/opera-developer cd /usr/local/portage/www-client/opera-developer wget -O opera-developer-24.0.1558.21.ebuild https://bugs.gentoo.org/attachment.cgi?id=381750 ebuild opera-developer-24.0.1558.21.ebuild manifest # install: emerge -av opera-developer # correct symbolic link to libudev rm /usr/lib64/opera-developer/lib/libudev.so.0 ln -s /usr/lib64/libudev. ...
