You need also the dev headers (probably called libpng-dev). Please
note that the "--enable" switches allow you to shoot yourself in the
foot, as it's try to compile the parts of mplayer you activated
whether or not you have the necessary headers.

So, WHENEVER you use --enable, please be sure that you're not doing
smth dumb. :-)
