Ah, yes!  Bingo.  Okay, fortunately it looks like at some point in the
past I added libpng to the install script options.  If you edit
install_script.sh and turn on INST_PNG, when you re-run I think it
will give a shot at installing libpng independently of the OS.  I
believe that'll fix the issue, but let me know how it goes?

Thanks,

Matt
