A much much easier way to do this is to simply download the official renpy launcher and use it to launch the game, or use it to rebuild it for your platform.
For future reference its much easier to just install the official renpy launcher and use it to launch games when they aren't supported on your system. I do it all the time to play windows only builds on my mac.
Not sure if this is welcome here but I do it pretty often over on F95 for games that seem to need it. But the OG linux only build is rough 8GB in size so I used UAGC too compress the game down to about 1GB, i also rebuilt the compressed version to make a PC/Linux, Mac and Android versions. So...
