The checksums warning is always true for default Solaris installs.
You can change it with "ndd /dev/udp something_or_other".  The
SIOGIFCONF sounds as though the compile went wrong somehow.  Try
compiling traceroute again, possibly using a different C compiler and
making sure that you don't have /usr/ucb in your path at all.

That's not correct; teh checksums warning is a part of teh traceroute code.

By default Solaris 2.x will have UDP checksums enabled; it's the traceroute
source code that doesm't produce checksums in the UDP packets it sends.
