[Pharo-project] Alien plugin? Status of VMMaker

Do any of you know of an alien plugin for linux? Is VMMaker alive and well on Pharo? I am getting close to (perhaps) being able to move some number crunching onto Pharo, but it will depend on external libraries and callbacks. My reading suggests that the existing FFI is unable to handle callbacks, and that plugins are required. Alien looks a lot closer to what I have working on Dolphin. Unless Alien is pre-built, it appears that I am stuck with setting up VMMaker?? That might not be all bad, because I am suspicious I might want to use a plugin for OpenSSL, but that is (so far) a little further away. I would be happy to bypass that learning curve for a while longer :) Bill
