It looks good

Maybe you could make the warning specific to using the 'apple-apple-apple' 
library-combo (ie, building using the Apple frameworks).  If you are using 
the 'gnu-gnu-gnu' library-combo, then the right thing to do might be to
source GNUstep.sh in your shell ?

It looks good.  I had a look around and I realized that most platform options
we have at the moment are set at configure time though.  Would that make
things easier ?  We could also use a longer expressive name there (you have
to type it only once), ie

./configure --enable-absolute-install-paths

that could set a variable (ABSOLUTE_INSTALL_PATHS = YES/NO) in config.make.  
The same variable could then be overridden on the command-line (as in, make 
ABSOLUTE_INSTALL_PATHS=NO) if needed for a special occasion, but I'd expect 
that most people will consistently either use the option, or not use it, so 
they'd set it once in ./configure and be happy.

How does this sound ? :-)

Thanks
