Thanks Neil.

To try out 2.6.2 I have removed 2.5.6 first, then I installed 2.6.2.
Now I cannot install 2.5.6 anymore:

emerge -vp media-video/avidemux:2

These are the packages that would be merged, in order:

Then I have removed both versions and I have installed version 2.5.6  
first. Then again

So, you must have been very lucky, and that's not portable.
