Bottom line, something in nmap or dnet is having difficulty getting
system routes, and it appears to be most common on *BSD kernels on
non-ethernet adapters.

Gianluigi, can you please send the output of "nmap --iflist" from  
nmap 4.01?

Can you also please send the output of your "ifconfig -a" on OS X?

And last but not least, would you be willing to try working your way
up from nmap 3.81 to 4.01 and let us know what is the first version of
nmap that breaks?  I know that is asking a lot, but it would be the
most valuable. Old distributions can be found here:
http://www.insecure.org/nmap/dist/

Thanks again,
  kx

Hi,
this is only a note; i know that this problem is known.
I try to use nmap on a ppp via gprs connection and the result is
WARNING: Unable to find appropriate interface for system route to ...
At this moment i don't have experience on a different connection.
I compile nmap 4.01 on Mac OSX 10.4.6.
libdnet is 1.10
I use without problem 3.81.
bye
