emacs-snapshot +gtk+x11 failing to run

[Andrew Todd]

After a recent "port upgrade outdated," I am no longer able to run
emacs-snapshot.

$ emacs-snapshot
dyld: Library not loaded: /opt/local/lib/libMagickWand.4.dylib
  Referenced from: /opt/local/bin/emacs-snapshot
  Reason: image not found
Trace/BPT trap


Any ideas? Thanks.
