You're welcome!!!! I am very glad it worked for you!!! Quake 3 is fun and a great showpiece. Now I feel like I didn't lose anything by upgrading to PR 1.2RC.
You will also be able to install Brain Party and any other application that depended on the GL deb.
Then I can install quake 3 deb file? at the moment it says dependancies are missing, could this lead to errors in the future?
Yes, that is what I did and it worked. Just be sure to place the libgles file in the MyDocs folder and copy and paste the root text into x and hit enter.
