Installing yasm on Amazon Linux

I am currently working on a project that requires me to build ffmpeg locally on an Amazon Linux instance.  I did a repo search and could find nasm, but ffmpeg didn’t like it at compile time.  Here is how to get yasm installed.  I am documenting this because I will probably need it again.  It is assumed you have already installed git-core.

git clone git://github.com/yasm/yasm.git
cd yasm
./autogen.sh
./configure --prefix=/usr 
make
sudo make install

Git is a handy little tool.
