FYI,

I ported Ruby, as well as the gtk2 and glade2 bindings to
my Neo1973 phone running the OpenMoko platform which is in turn
based on the OpenEmbedded platform. So this is ruby running
on arm-linux-gnueabi.

Info and packages on:

Screenshot of simple ruby+glade app:

(the neo has a 480x640 screen at 283 DPI so this screenshot
seems bigger than it is :)

Bye,
Kero.
