libpng in unix is tricky: some distros bundle old release 1.2, whereas other have newer 1.6. They're somewhat incompatible so library filenames are different. Watching your log, seems that tilengine was built against older release 1.2. When you recompiled it, you linked against your own libpng version so everything works now.
I'm glad you have it working, feel free to ask any other issues you may have!
