I did say no more updates, but I can maybe have a look later to see if I can make a 64 bit Ubuntu build of the last version without too much extra work. No promises though.
So I had to do a fresh install of Ubuntu on my Linux machine and fix a couple things before it would build again but I seem to have something working. I haven't had a chance to test it extensively but if you send an email to ninjadodogames[at]gmail[dot]com I can send you a build.
