The difference of pstoimg between revision 1.16 and 1.19 includes
the line:

  $trans_color = $TRANSPARENT_COLOR||'gray85';

If your pnmtopng can not recognize the color name 'gray85', you 
may fix the problem to use '#d9d9d9' instead of 'gray85'. Please
try to

1) edit the pstoimg script directly,

or 

2) set the environment variable TRANSPARENT_COLOR to "#d9d9d9"
  (but I do not know how to set the environment variable on the 
  Mac OS X).
