You can try this:
Go to the directory that the libglx.so.1.0.3123 exists in, and type in the following:
ln -s libglx.so.1.0.3123 libglx.so.1
ln -s libglx.so.1.0.3123 libglx.so
At least, I think this is right. This should create symbolic links that will basically mean that whenever a program requests libglx.so or libglx.so.1, it will be redirected to libglx.so.1.0.3123. You may wish to type "ln --help" first. I may have the order wrong (Not in Linux atm to check...).
