Yes, this is a known issue, but it’s hard to fix because of the way Mac OS X handles library dependencies. You can use install_name_tool to change the id of the dylibs in question, or you can put your binary in a subdirectory of /Developer/Panda3D in order to work around this. Or you could copy the Panda3D dylibs so that they are in a …/lib/ directory relative to the location of your binary.
