I compiled nmap from pkgsrc on the same Mac, and then I get the same  
errors as on NetBSD.
(Could it be due to that pkgsrc relies on libpcap and pcre from the  
pkgsrc tree.)

nmap-5.21 ->
libpcap-1.0.0nb2    System-independent interface for user-level packet  
capture
pcre-8.00           Perl Compatible Regular Expressions library

I also compiled the SVN version (in pkgsrc on NetBSD), and it fails  
the same way as before:

bash-4.0# ./work/nmap-5.22/nmap --iflist

Starting Nmap 5.21 ( http://nmap.org ) at 2010-03-23 18:52 CET
INTERFACES: NONE FOUND(!)
WARNING: Unable to find appropriate interface for system route to  
193.10.5.1

127.0.0.1

(I says Nmap 5.21 ? )
