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.

They are text files created by libtool and appear to describe the library. Before the release of OS X we determined that .la files were unnecessary for MacPorts generally so we remove them on 10.9 and later. ImageMagick however uses these files to load its modules, so we keep these files for the ImageMagick port and a couple others.

Ok, that's identical to mine, so there's no problem there.
