Hi, This seems to be a problem for a few of the dynamic libraries. Running otool on libboost_filesystem, for example, gives: otool -L /opt/local/lib/libboost_filesystem-mt-1_35.dylib /opt/local/lib/libboost_filesystem-mt-1_35.dylib: /opt/local/lib/libboost_filesystem-mt-1_35.dylib (compatibility version 0.0.0, current version 0.0.0) libboost_system-mt-1_35.dylib (compatibility version 0.0.0, current version 0.0.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.4.0) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.3) The install_name of libboost_system-mt-1_35.dylib is missing the absolute path. How should this be addressed? Sancho
