#ffmpeg is usually pretty active, but maybe not in your timezone..

The file in question is in the root of your ffmpeg source tree.

So you are asking it to include the external lame library and the  error you
list above is telling you that it cannot find a version of that library no
earlier than version 3.98.3                                                        

You need to install a version of lame that matches this criteria, making sure you
include the "-devel" packages for the compiler to link against.
