Hi Bill, thank you for your reply! :) I experimented with kinds of "not compiling it natively" like distcc, crosscompiling and such. May be me of may be a problem with the tools/ the environment/the setup or whatever: The results were corrupted systems every time. This costed me even more time than waiting for "Calculationg dpeendencies...". So I am back to natively compiling that stuff... Best regards, Meino
