Spakman, thanks a lot, I've already found your useful site the day before yesterday. From:
http://code.scottishclimbs.com/maemo.../binary-armel/
I took:
libruby1.8_1.8.6-p110-1_maemo4_armel.deb
ruby1.8_1.8.6-p110-1_maemo4_armel.deb
ruby1.8-maemo_0.4.0_maemo4_armel.deb
and all worked perfectly. By chance, I had a copy of:
irb1.8_1.8.6-p110-1_maemo4_all.deb
and added a ruby console without any problems. Spakman, can I e-mail you this small file or upload it anywhere for the others ?
The big pro of Tom Swindell's ruby port are the great hildon bindings. It's a pity that he does not manage to get his site up again after all this good work!

Bob.
