libpng is at 1.6.9 in MacPorts; no surprise it can't find libpng 1.5. As to why libmodplug fails I don't know; you would have to attach main.log for somebody to be able to debug, but...
Errors were solved by manually installing libmodplug and libpng15 (./configure --prefix=/opt/local) from non macport sources;
That's the worst thing you could have done. You should '''never ever''' manually install software into MacPorts' prefix. Even worse, that operation has probably overwritten files installed by MacPorts, e.g. `/opt/local/lib/libpng.dylib`, which other binaries use. That might have broken these binaries. Basically you've gotten your MacPorts installation into a state where builds are going to fail for random reasons and no way for the port maintainers to help you in figuring out what went wrong. There's also no easy way to go back to a consistent state short of uninstalling all ports, deleting MacPorts and re-installing from scratch. -- Ticket URL: <https://trac.macports.org/ticket/42645#comment:1> MacPorts <http://www.macports.org/> Ports system for OS X
