We already had such breakage with older distutils versions (pre 1.0 I th=
ink), and 
my way to solve it was:

if hasattr(distutils.dist.DistributionMetadata, 'get_keywords'):
    setup_args['keywords'] =3D "wiki web"

if hasattr(distutils.dist.DistributionMetadata, 'get_platforms'):
    setup_args['platforms'] =3D "win32 posix"

apply(setup, (), setup_args)



Some official distutils "capability" mechanism would be nicer, of course=
. Don't 
check version numbers!
