Wow, this is really powerful stuff, a long read, but well worth it. By recombining and reusing all their technology they seem to be able to move into more and more territory. It is closed source and (very) expensive, and I don't like the syntax, but we sure can get good ideas from them. Thanks for sharing the link. Sven

I guess that this is all linked to files.pharo.org who is not that reliable. I am getting errors from http://files.pharo.org/vm/src/lib/ when building the VM for the third party libs. And also, regular occurences of the problem you describe. Can't we get something more solid?

Give it a try on an empty folder... I think that fails if you already have the VM or image.
