Maybe you can use Parenscript.
No need to apologize: I planned to add text with the instructions to play, but the time was not enough.
It may be necessary to use a recent version of McCLIM, try updating the distribution of quicklisp.
Did you press the 'n' key? That begins the game.

That means that you don't change the directory to /home/borodust/quicklisp/local-projects/mc-wolf3d before load the game.
I you are using the code, change the directory to mc-wolf3d/ before load the system.
Yes, it has some strange problems that I have not managed to reproduce and fix. If you are using stumpwm, run the game in a floating group.
What variable? After your comment I tried the code and the executable without problem.
