Comment (by lpancescu):

 After a first attempt to bring it up to date: the new version uses
 configure and depends at least on
 https://github.com/ImageOptim/libimagequant, which isn't available in
 MacPorts yet.

 I initiated a port abandonment request, #54532 (I hope someone can take
 over maintaining it).  Sorry.
