[email protected]_0+x11 isn't finding a shared object libgs.9.21.dylib (which is there in /opt/local/lib, so presumably a -L option isn't being passed?). This causes clips upgrade to fail (because it wants to use ps2pdf on a couple of its documentation files). It also seems to cause a problem with ImageMagick, as reported by the check of binaries for linking errors.
Perversely, the ghostscript upgrade seems to succeed, meaning I had to delete it and rerun it with port -k upgrade ghostscript, to get a log file (attached). Falling back to 9.19_0+x11 make everything else happy again. This was on El Capitan, but seems also to be happening on Sierra.
