I had to make the change below so that ‘tome4’ would behave as one would
expect.  However, the game doesn’t work for me: it creates an X11 window
that immediately disappears; after that, the engine is running
(displaying its activity in the console), but there’s no open window.

The problem can be reproduced with:

  ./pre-inst-env guix environment --pure --ad-hoc tome4 

Could you check if it works for you?

Thanks!

Ludo’.
