The output of 'otool -l' lists (amongst others) the value of LC_VERSION_MIN_MACOSX which is the deployment target. Both can also be found using macholib ;-) Ronald _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
