but coinflip is no a gem, it's just a directory resulting from my trying

I found out that there is, apart from glade, also a glade-gtk2 in my
xubuntu system. So I got to a fresh computer with a fresh xubuntu,
installed glade-gtk2 and visualruby.
I got to my ~/visualruby_examples and typed vr all_widgets and then
tried to edit the glade file, after changing the glade command line from
glade-3 into glade-gtk2 in Tools->Settings. But I got a window with the
nice tools, but an empty editing field. Plus these error messages in the
terminal:
