Thanks for the feedback. One clarifcation, the commend below selects the Qt 
OpenGL graphics toolkit (i.e. does not use gnuplot).

        graphics_toolkit (“qt”)

Some of the errors you reported were produced by gnuplot. Does the result below 
also work?

        graphics_toolkit gnuplot
        setenv GNUTERM qt
        close all
        plot (rand (3))

In any event, since the app-bundle you obtained from the wiki did not include 
“—universal” when installing fontconfig, it is likely this is the root of the 
problem.
