DNS resolution not working with RPM installation on Fedora-12 x86_64

[Bert Sutherland <bert842 () yahoo com>]

I recently completed a net install of Fedora 12 x86_64 and I noticed that all of the instances of nmap installed via 
RPM package were unable to perform DNS resolution.  I tested this with both 32-bit and 64-bit RPM installers for nmap 
5.30BETA1 and neither were able to do DNS lookup.  I had no better luck with the nmap 5.21 64-bit installer either.  I 
don't know if this might have anything to do with the fact that this was on a laptop using a wireless connection; 
probably not, but maybee....

However, DSN resolution worked in all cases where I downloaded and compiled the .tar.bz2 source.  Please see the 
console session below for further detail.
