Ruby & gui and ssh

Is possible to show working ruby gui?
wxwidgets, GTK+, QT, SDL2 etc.

I need irb and normal ssh -2 with pam verification.

Clockwork likely is using a derivative of an existing OS for the Game Shell, so those GUI interfaces should have no problem running. Unless if they’ve done something that breaks the compatibility of those packages with the OS in some way (which is highly unlikely), anything that works on other OS like the Raspberry Pi should work on the Game Shell.
