I had it working before but don't know how I did itthis is what the readme file says (in part)
Linux
You'll need to make sure the appropriate OpenGL drivers are installed, plus these libraries:
* libSDL 1.2
* libSDL_image
* OpenAL
(Note: To use the client provided with the Linux package, you will need OpenAL-Soft instead of OpenAL, otherwise you will need to compile your own client if you would rather use normal OpenAL).                     

I know what they want me to do but googling it is confusing. HOw do I do this. this is what I was told to do and the result:

bmike1@Presario1:~$ sudo apt-get install xlibmesa-gl xlibmesa-glu mesa-utils libgl1-mesa-dri libgl1-mesa-glx libgl1-mesa-dri:i386 libgl1-mesa-dri
