You can ignore the warnings for now.

The tic/toc commands are giving results are a slower than I'm used to.  When I 
run the same commands I see similar results the first time. However, if I run 
the commands as below, then the timing is faster and the 

tic (); print test.eps; gnuplot_eps = toc ();
tic (); print test.eps; gnuplot_eps = toc ()
tic (); print test.png; gnuplot_png = toc ();
tic (); print test.png; gnuplot_png = toc ()

The eps is produced in about 0.1 sec and the png in about 0.4 sec.  As your 
fltk_png is about 0.5 sec, I expect you'll get similar results.

Can you give us an example where the timing is slow?
