What version of gnuplot are you running? I get similar errors/warnings with 
gnuplot-4.2.6 (missing terminals), but no errors with gnuplot-4.4.

Fig2dev converts from xfig format to other graphics formats. It is part of the 
transfig package.

        http://xfig.org/art17.html

In any event, I need to handle a missing pstoedit or fig2dev in a more proper 
way.

p.s. I've attached you're output from my script for others to see.
