    config files/resources"  Include the ImageMagick resources in the bundle.
    Note that this only works when the user does not have a version installed
    in the same prefix as the one originally built for the bundle.  This should
    be okay since the official package is built with a long obscure prefix.
 -  Fix bug #392693: "Conflict between bundled and system libxml dylib"
    The official package no longer uses the DYLD_LIBRARY_PATH magic.  Instead
    all paths within the dylibs, executable and shared objects get rewritten
    to be relative to the executable.  Note: Packagers will need to install
    Macports into a PREFIX of 50 characters in length to allow enough space
    within all the libraries for path rewriting.
