Tk either picks the system libpng, or if missing, the bundled libpng. The system libpng is only used if the devel files are available, which does not seem to be the case on your system. So what you can try is to install the libpng-devel package, and retry compilation. For me it means to check if the bundled libpng can be updated to work also with RHEL 6.

I got the same error on Ubuntu 18.04.
