So, should setuptools maybe check the deployment target and use that to decide whether to chdir-hack or to use -install_name @loader_path/blah.dylib? That won't make the current platform tests and build customization any more complex on a fundamental level. I already have to decide whether to use a chdir loader (not needed at all on Windows) and whether the loader should use dl (Linux) or not (Mac). So, adding an environment variable check doesn't sound like a big deal. Do any OS X versions prior to 10.3 even have Python installed, btw? I'm figuring I can live with not supporting those, though I should double-check what OSAF is targeting, of course. _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
