I can start each of "image" and "mandelbrot" from the command line.

I can give each a link-name, as you showed.

But I still cannot get any of the ExtendGraphics packages delaunay.m, 
mandelbrot.m, Contour.m to load properly inside Mathematica -- in each 
case getting an error that the specified file "is not a MathLink 
executable".

The value of DYLD_LIBRARY_PATH is empty, and what I read says this 
variable is not supposed to be used in OS X anymore.

(I'm getting well beyond my depth here...)
