	So we have established that the shared png libraries exist. But
the configure script is having trouble finding the png.h header file.
This is usually the difference between having, say, the "png" package and
the "png-devel" package. If you're using some kind of managed package
distribution (like RedHat with RPMs or Debian with DEBs), look for some
kind of png-devel package. Otherwise, go to libpng.org and download and
install the latest version of the library, which will install the devel
material by default.

	If you take the latter route, be careful about having more than 1
version of png running around your system (since the new version will
likely install in /usr/local/lib by default). This could cause you
confusion down the road (e.g., a package claims you have ver.x and it
needs ver.y, you maintain that you have ver.y when in fact you have both
and the package is finding ver.x).

	Hope this helps...
