Hi John,
Where did you install gnuplot (the program, not the module)?  The execution path (os.environ['PATH']) is considerably different in standalone Python than in Chimera's IDLE shell.  I suspect that the gnuplot executable is not on IDLE's PATH (the Gnuplot module by default tries to run gnuplot simply as 'gnuplot').  If the problem is with PATH, your options include modifying os.environ['PATH'] before importing Gnuplot, or changing the Gnuplot module's options like so:

        import Gnuplot
        Gnuplot.GnuplotOpts.gnuplot_command = '/bin/mygnuplot'

Dear chimera power-users:

I can use the gnuplot.py library from the python command line without  
issue.  However, when I try to do the same in IDLE under chimera, I  
get a broken pipe error.

  Any suggestions?
