I wrastled with the program according to the info in this question. Now it is installed but I can't figure out how to run it. A friend running the same version of Ubuntu had no problems getting it to start after installing it the same way.
This is what I've done:
$ ./Psychonauts
./Psychonauts: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
So I went ahead and:
$ sudo apt-get install libstdc++.so.6
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libstdc++.so.6
E: Couldn't find any package by regex 'libstdc++.so.6'
It should be noted that I only started using Linux a few days ago.
Okay, so I did manage to install apt-file and apt-file update.
However then we hit another snag.
usagiyojimbo@Usagi:~$ sudo apt-file find libstdc++.so.6
[sudo] password for usagiyojimbo:
E: The cache is empty. You need to run 'apt-file update' first.
I have done that, when I do it says:
File is up-to-date.
Ignoring source without Contents File:
a link they won't let me post
Or
File is up-to-date.
Downloading Index a link
No Index available.

I am still getting the same error when I try to run Psychonauts.
sudo apt-get install libstdc++6
