SOLVED ok i put libboost_python-1_33_1.dylib in a "standard location" like pointed out here http://developer.apple.com/documentation/DeveloperTools/Conceptual/DynamicLibraries/Articles/UsingDynamicLibraries.html in my case: ~/lib i am still not sure what was wrong about using DYLD_LIBRARY_PATH
here is a Summary: To use your boost.python extension module on OSX: 1) get boost.python 2) make sure libboost_python-1_33_1.dylib is in a "standard place" 3) link your extension using the -bind flag and -L/libpath -lboost_python-1_33_1 4) name it .so like myextension.so 5) import it in python using "import myextension" Thanks again to Torsten and Ronald, Stephan _______________________________________________ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
