Installing Quake2 with potato

[Chris Hoover <wax_man@bellsouth.net>]

I'm trying to get quake 2 to install.  However there seems to be some packages
missing.  
When I try to install quake2-bin, I get the following messages:
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

Sorry, but the following packages have unmet dependencies:
  quake2-bin: Depends: libgl1 but it is not installable
E: Sorry, broken packages 

When I try to install quake2 I get these errors:
Setting up quake2 (3.20-4) ...
ln: cannot create symbolic link `/usr/lib/games/quake2/opengl32' to `/usr/lib/libGL.so.1': No such file or directory
dpkg: error processing quake2 (--configure):
 subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
 quake2
E: Sub-process returned an error code (1)

What do I need to do differently to get quake2 installed?

thanks,
