Getting Flash to work in Opera

I have always liked Opera as a web browser but the standard installation in Gentoo leaves Flash Player broken.
I have seen a useful link to get Flash Player up and running in Gentoo and consequently Calculate Linux.

It shows you how to tell Opera to use a specific version of Flash Player on your system and get it working.
Opera is faster than most browsers and has an integrated mail client.

I use Opera on CLD. It works with adobe-flasnplugin out-of-box.

Thank you. (But it’s: www-plugins/adobe-flash)
