noon% traceroute -g 1 -g 1
traceroute in free(): warning: page is already free.
Version 1.4a5
Usage: traceroute [-dDFPIlnrvx] [-g gateway] [-i iface] [-f first_ttl] [-m max_ttl]
        [ -p port] [-q nqueries] [-s src_addr] [-t tos] [-w waittime]
        host [packetlen]

That's a bit older 1.5_ALPHA2.
