Builder Wizard failed


During the process of compilation/installation of kdenlive from the Builder Wizard, I have a message saying that "unable to configure ffmpeg". I tried to follow the HOWto from Suse (I have Suse 11.2) adding the option "--enable-nonfree", but it does not work. I use the wizard because it was the only way to get avchd files played by kdenlive when I was with Suse 11.0. If I install directly from the packages it didn't work. So I tried again with Suse 11.2, but I assume that the versions of the ffmpeg and kdenlive builder wizard were upgraded since then, so I don't know where to look to solve the problem.
Thanks for your help.
