This is correct. The default delete command does what it says: It deletes the 
respective default and therefore the command default read can no longer read 
it. Admittedly, the message could be improved to say that the default does not 
exist at all.

Don't do that. Using the name art for the cairo backend (selected with 
--enable-graphics=cairo) would be confusing everybody. The --with-name option 
really makes sense only if you are installing different backend bundles 
(GNUstep provides art, cairo, and xlib) in parallel and want to be able to 
switch between them, which is achieved by changing the GSBackend default. If 
you only use a single backend bundle, it is best to stick to the default name, 
which is gnustep-back for that matter, and leave the GSBackend default unset.
