libharu build fails with libpng 1.5

[jwhowse4]

I am running Lion 10.7.4 with XCode 4.4.1. After upgrading to libpng 1.5, libharu fails with the following error message.

I found a patch at ​http://pkgbuild.com/~ioni/libpng-1.5/libharu-2.2.1-libpng-1.5.patch. The attached Portfile and patch fix the problem for me.

Thanks for the patch, I was waiting for libharu's RC, that already builds with libpng 1.5, to become stable before upgrading.
