Many thanks !   I just got fed up playing guessing games with Fedora Core 20 
and gave Ubuntu 14.04 a shot.  To my surprise, it has come a long way and 
everything I tried worked at once !

Ivan had a script for installing GNUSTEP a while back but I'll try this way.

I know its a little tricky as the dodges and cautions you've kindly shown 
indicate.

Thanks again,
Dr. J.
