Player/Stage installation

Hey everyone!!!

I hope you're all doing well. I have good news. I've already successfully installed Player/Stage and I can open the .cfg files. Tomorrow with Laura I'll try to see how playerjoy works and hopefully get to work with the robot as soon as possible.
The problems I had while trying to test stage by opening a .cfg file were:

•  error while loading shared libraries: libplayerdrivers.so.2.2: cannot open shared object file: No such file or directory
• err: unable to open color database: No such file or directory (stage.c stg_lookup_color)

To solve the first one I have to export the libraries every time I open the Terminal, and I know that this can be made automatically by putting it in the bashc file or something like this but I don't exactly know how to do it so if you could help me with this it would be really great.

And in order to solve the second problem, I had to create a file called rgb.txt that was deleted from the newest versions of ubuntu (they thought it wasn't necessary anymore) so you have to create it with some information given in this link:

I think that would be all, regards!!!
