I probably should've mentioned that it's best to use an Nmap binary  
that's been compiled with debug symbols :) I'm guessing you compiled  
Nmap yourself, so try this: Once you've untarred the nmap tarball and  
done "cd nmap-4.01", do the following:


CFLAGS=-g CXXFLAGS=-g ./configure
make
gdb ./nmap

Then use the gdb instructions I provided earlier.
