	# Normally tor uses a bundled libevent fragment to provide
	# asynchronous DNS requests.  This is generally a bad idea, but at
	# the moment the official libevent does not have the 0x20 hack, so
	# anonymity is higher with the bundled variant.  Remove patch as
	# soon as upstream has installed the autoconf option to use
	# system's libevent.  This hasn't happened, so we
	# have to live with the bundled libevent for this release, as the
	# current version in tree won't suffice for tor to build
	# See http://bugs.noreply.org/flyspray/index.php?do=details&id=920
	# for upstream's report
	# Let's revisit this when libevent-2* is unmasked
	# use bundledlibevent || epatch "${FILESDIR}"/${PN}-0.2.1.5-no-internal-libevent.patch
