Friedrich, I recall having success with the vm as-is and just patching the image. One thing the vm certainly should do is tell us the translations it makes. I think it is always a good idea to know which port was actually opened, or failed to open :) Double that for external libraries, but that's another story. Try the attached. It is basically lifted from Squeak (to handle numbers and names) and then tweaked to avoid the silent failure trap.

(not just by Number) There are patchs for the plugin. I wonder how do I build such a new plugin? Or can't I use that in Pharo? Regards Friedrich
