New submission from Matthew Scott <m...@11craft.com>:
Using Python 3.2.2 and Python 3.3.0a2 (installed via 64-bit installers in
official DMGs on python.org), 'distutils.util.get_platform()' returns an
incorrect OS version when running on Mac OSX 10.7.
Using Python 2.6.7, and Python 2.7.1 (the versions included with Mac OSX), the
output indicates 'macosx-10.7' correctly.
> for version in 2.6 2.7 3.2 3.3; do python${version} -c "from __future__
> import print_function;import
> distutils.util,sys;print(sys.version.split()[0],distutils.util.get_platform())";
> done 2.6.7 macosx-10.7-intel
2.7.1 macosx-10.7-intel
3.2.2 macosx-10.6-intel
3.3.0a2 macosx-10.6-intel
Some packages make use of this in their setup.py to determine the proper
location of libraries.
For example, the 'readline' distribution's setup.py does so here:
https://github.com/ludwigschwardt/python-readline/blob/6f0e801fa1632fcbb0e005eb9709aaa6051a0f28/setup.py#L33
It fails due to the incorrect assumption that it's running on 10.6 instead of
10.7. Excerpt from "python setup.py bdist_egg":
