ogmrip's './configure' does not want to complete because it does not want a cvs version of mplayer and the latest version of mplayer in portage is a cvs version. I have made a ugly patch that disables this check and forces mplayer version recognized by ogmrip to be 1.0-pre7 So far, it works pretty good. Another solution would be to make ogmrip incompatible with cvs versions of mplayer.

Created attachment 82087 [details] The ebuild applying the patch. Beware of the need to rerun autoconf
Thanks! it's on cvs.
