You can use strace to debug the program you're trying to execute - this should show you exactly which directory paths it's looking in for Then you can run find /usr -name* or an apt-file search. Typically though, you can just install or reinstall the appropriate glx package - for example:

# apt-get install --reinstall libgl1-mesa-glx
