Description

For a specific reason, `which stat` = /opt/local/libexec/gnubin/stat, on my Mac. o.a.h.f.HardLink checks for os.name, detects it's a MacOSX, and assumes that stat points to /usr/bin/stat, and uses -f%l as arguments, which fails. The upcoming patch explicitly sets stat to use /usr/bin/stat on Mac OS. In 0.22, this code is part of o.a.h.f.FileUtil, and in 0.23 and trunk it is in o.a.h.f.HardLink. Both patches forthcoming.
