# Require sandbox-2.2 for bug #288863.
# For xattr, we can spawn getfattr and setfattr from sys-apps/attr, but that's
# quite slow, so it's not considered in the dependencies as an alternative to
# to python-3.3 / pyxattr. Also, xattr support is only tested with Linux, so
# for now, don't pull in xattr deps for other kernels.
# For whirlpool hash, require python[ssl] or python-mhash (bug #425046).
# For compgen, require bash[readline] (bug #445576).
