I guess when compiling NSBitmapImageRep+PNG.m, you got a warning about 
implicit declaration of function png_sizeof?

OpenBSD ships 1.5.10.

The following API are now DEPRECATED:
   png_info_init_3()
   png_convert_to_rfc1123() which has been replaced
     with png_convert_to_rfc1123_buffer()
   png_data_freer()
   png_malloc_default()
   png_free_default()
   png_reset_zstream()

The following has been removed:
   png_get_io_chunk_name(), which has been replaced
     with png_get_io_chunk_type().  The new
     function returns a 32-bit integer instead of
     a string.
   The png_sizeof(), png_strlen(), png_memcpy(), png_memcmp(), and
     png_memset() macros are no longer used in the libpng sources and
     have been removed.  These had already been made invisible to
applications
     (i.e., defined in the private pngpriv.h header file) since
libpng-1.5.0.

The signatures of many exported functions were changed, such that
   png_structp became png_structrp or png_const_structrp
   png_infop became png_inforp or png_const_inforp
where "rp" indicates a "restricted pointer".

here I see that png_sizeof() is just a #define to sizeof()

so exchanging it with sizeof should just work?
