Hmm, can you tell us more about the platform? What version of
OpenSolaris (uname)? Are you sure it's gmake 3.81?

The reason I ask is that we had reports of successful builds on
OpenSolaris recently, with only a small problem keeping Nping from
building.

And things like this:

should not be necessary with GNU Make, because there's an
"export NBASEDIR" earlier in the makefile.

How slow is DLPI compared to the alternatives? I'm afraid I don't know
much about this.

As far as I know, SIOCGIFHWADDR is already used (on an AF_INET socket)
to get the interface list on OpenSolaris (in tcpip.cc). Does that not
work? What does "nmap --iflist" say?
