Looks like there might be a problem with your installed libpng.  I had
a similar problem when I had an older version of the library
installed, and openvrml (which requires something later) couldn't get
all the later functions out of the stale header file...

I'd check the machine and make sure you don't have stale libpng
installed somewhere...

HTH.  Thanks for the time and attention--
