I'm betting you hit the same premultiplied alpha problem/limitation
reported in SDL_image.
http://bugzilla.libsdl.org/show_bug.cgi?id=868

The workaround/solution was to add a block of code at the end of the
loader to un-premultiply the alpha (now in the codebase).

If that is indeed the problem and the workaround works, I recommend
you submit the fix for osgdb_ImageIO. Also, please file a bug
report/feature request with Apple. The more reports they get, the
better.
