As I found out this is an issue not only with keyword, but
affects everything where util.realpath is now used and the
corresponding tests.

It turns out that on darwin util.realpath uses posix.realpath
which in turn is special-casing darwin in a workaround for
os.path.realpath. At least here on MacOS 10.5.8 the darwind
workaround actually causes the failure on darwin ;-),
os.path.realpath gives the correct results just fine both with
Apple-shipped Python 2.5 and my Python 2.7.

Could other MacOS users test latest stable to verify?

thx
