Comment (by kencu):

 one possible solution is to use the {{{Makefile-nolib}}}, which uses the
 installed versions of png and zlib.

 Doing that needs a couple of small tweaks to the include paths, and use
 this debian patch:

 https://salsa.debian.org/debian-phototools-
 team/pngcrush/-/blob/master/debian/patches/ignore_PNG_IGNORE_ADLER32.patch?ref_type=heads


 and presto:

 {{{
 % port -v installed pngcrush
 The following ports are currently installed:
   pngcrush @1.8.13_0 (active) requested_variants='' platform='darwin 24'
 archs='arm64' date='2024-12-24T00:02:39-0800'


 % otool -L /opt/local/bin/pngcrush
 /opt/local/bin/pngcrush:
         /opt/local/lib/libpng16.16.dylib (compatibility version 61.0.0,
 current version 61.0.0)
         /opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current
 version 1.3.1)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1351.0.0)
 }}}
