Do still show us the contents of the .la file: cat /opt/local/lib/ImageMagick-6.9.11/modules-Q16/coders/heic.la Maybe there is an obvious error in there. When I search Google, I do see lots of reports of the "convert: unable to load module" "file not found" error from lots of other people who are sure the file exists, so the error message appears to indicate any problem loading that module, not necessarily due to the file being absent. Many people end up finding that there was a problem with one of the libraries that the module depends on. MacPorts rev-upgrade should identify such problems and rebuild any broken ports. If you've disabled the automatic use of rev-upgrade, try running it manually now with "sudo port rev-upgrade". Maybe it will find that ImageMagick or one of its dependencies needs to be rebuilt and then it might work.
