Did you mask libpng 1.5 ? If you did, this bug is INVALID. Ditto, if you're mixing stable and unstable.
yep, media-libs/libpng-1.4.8-r2 is unstable, Stable is media-libs/libpng-1.4.8, and it is slot "0"
Mixing stable and unstable is at your own discretion - meaning: any such bugs are your own. 1.4.8-r2 has "1.4" as it's binary only - in unstable packages either build and work with 1.5 or are in the process of getting fixed.
