I managed to build a working SqueakSource server image using the instructions from http://source.squeakfoundation.org.
With this predefined image you are able to run an own local SqueakSource repository server very easily.
Cees De Groot will host the image and put a download link onto the project page tomorrow. Here is a short preview of the image and the server running on localhost:
Many thanks to Doug Way for the instructions, the SqueakSource authors for this nice piece of Software, Cees for hosting and others who helped to make it available.
