Have you looked in loader_png.c? We had to patch that file in 1.4.0,
changing a deprecated function:

-                png_set_gray_1_2_4_to_8(png_ptr);
+                png_set_expand_gray_1_2_4_to_8(png_ptr);

But it doesn't look like that's your problem. Perhaps you're using a
newer libpng? I haven't looked at those lines, so I can't tell.
