The config.log file is where I would look to understand why this is happening.

Any reason why you don't want to use the emacs or emacs-devel ports that are already in MacPorts? They do have an +imagemagick variant you can use.

Just to make sure we're on the same page about terminology, if you're referring to the -devel packages offered in some Linux package management systems, which provide headers and other files needed to build something against a library whereas the actual library files would be in a non-devel package, MacPorts doesn't do it that way. In MacPorts, the headers, libraries and binaries will all be together in a single port.

We do have some -devel ports, as I mentioned emacs-devel above, but they have a different purpose in MacPorts: The -devel port will offer a (usually more recent) development version of the software while the non-devel port will offer a stable version of the software.

AppKit, being a part of macOS, won't be in a port; it'll just be there in the OS.
