Adding -ldl to linking command works.
Shouldn't this be tested at ./configure level?

This reminds me that I haven't corresponded to this thread:
http://seclists.org/nmap-dev/2007/q4/0195.html which is also about
the same issue.

I just tried it in my Ubuntu 7.10 system, and so I can confirm this
on two 7.10  systems. Please also note that I tried with and without
pre-installed pcre, liblua, libpcap, libstdc++, etc. too, as Kris
and Eddie suggested, but the issue still persists.
