Since DCMTK is build as shared libraries some plugins fail to load on Mac OS X or in worst case MITK crashes on start up. The reason for this is that the install name of the DCMTK dylib is wrong. Instead of the absolute path to the DCMTK library it contains just its name. On Mac if a library is not in a dedicated location where the linker automatically looks for it the library has to have the path in the install name
