I have a more general question in exact the same regard:
Was the lates greates window brl-cad kit built with MGED GUI; yes or no
I no - why not?
I yes: what do we have to install on our machines Windows, UBUNTU, FEDORA ... (i am not an expert) to make this tool chain detecting X11 nad tcl/tk files and as a consequence allow make and make install to fullfill it's job?
