Not used linux before and learning, i get this error when i try to load the game.
./Big Pharma.x86: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory

All the games installed via steam are working.
Tried to find how to install Gog's version of steam but cant find the download link.

everything is uptodate as far as I can see. I have installed the game and the dlc pack, shouldnt be any missing files?
