  15 Feb 2011; Alexis Ballier <aballier@gentoo.org> libass-0.9.11.ebuild:
  drop png useflag: it is only needed for the test program that we do not
  install and causes libass.so to be linked needlessly to libpng... moreover,
  it doesnt build against libpng15, bug #354997

-> fixed

see $URL for the proposed fix upstream.
