host belongs to bind-utils-9.1.3-3. I use xtraceroute component now but it
may belong to bind.

It appears that you are using a version of "host" that
doesn't support the
"-x" switch. Get the version by Eric Wassenaar
atftp://ftp.nikhef.nl/pub/network/ (Or see the Xtraceroute web page.)
It's fixed in xtraceroute-0.9.0-4. You will fint it in next release rawhide.
