google now offers a rpm for their plugin. however due to some things that google does not seem to understand you are better to stick with alien workaround
after some waiting finally google chat video/audio work on linux too.
here is what I did to get it working on opensuse 11.3 32 bit.
you should have activated
the packman and
the contrib repo
sudo zypper ar http://download.opensuse.org/repositories/openSUSE:/11.3:/Contrib/standard/ Contrib
(it is in oss, I had some mushrooms for breakfast that day, the only explanation I may find for the wrong packman reference)
sudo zypper in libopenssl0_9_8
from contrib install alien
sudo zypper in alien from the google webpage...
