Re: SWI-Prolog and Mac OS X 10.9 Maverick, and XPCE

I just tried swi-prolog on Mavericks, and encountered a similar but somewhat
different problem.

swi-prolog itself seems to run correctly. However, xpce does not run. The
simplest example
occurs with :- use_module(library(pce)) followed by manpce. The exception
says that
pce_principal:pce_init is undefined, and says further that
/opt/X11/lib/libXpm.4.dylib is
not loaded. 

On my machine, that library is located at /usr/X11/lib/libXpm.4.dylib.

Is there any (easy) way I can redirect swi-prolog to the correct library?

I tried this with both 6.6.0 and 7.1.0, downloaded as disk images from the
website.
