	# Bug 348816 & Bug 341741: The previous ebuild default of
	# /usr/bin caused unnecessary conflicts with other
	# packages. However, the default nmh libdir location causes
	# problems with cross-compiling, so we use, eg., /usr/lib64.
	# Users may use /usr/lib/nmh in scripts needing these support
	# programs in normal environments.
