No, I'm writing about non stdlib extension modules.

Right? No, because the act of compiling your .egg fixes the specific version (e.g. numpy==1.3) to keep the ABI compatible with the version of numpy installed at extension module compile time. Whereas the install_requires is about API compatibility, and could thus be numpy>=1.2, for example. (For pure Python modules, this isn't a problem because there is only an API version to worry about. But with compiled extensions, there is also the ABI version to worry about.) _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
