I am installing ffmpeg utility, but I am facing libmp3lame >= 3.98.3
not found not found error. I am able to find lame-3.99.5-1.el6.rf.x86_64.rpm

What worked for me was building lame from source. Download lame from here: https://sourceforge.net/projects/lame/files/lame/3.99/, then extract and install:
tar -zxvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure
make
sudo make install
Check to see where libmp3lame.a is:
locate libmp3lame.a
Its probably in /usr/local/lib.
Now when you go to configure ffmpeg, try adding that path to the end of your ./configure string. For me it made the difference. e.g.:
--extra-ldflags=-L/usr/local/lib
