Thanks for this report. It looks like it was a bug in the script; it was
searching relative to the current directory rather than relative to the
installation directory. I think it is fixed in r31612.

You can try applying the fix yourself by changing this line:
  local gi = assert( GeoIP:new("nselib/data/GeoLiteCity.dat"), "Cannot read Maxmind database file in 'nselib/data/'.")
to this:
  local gi = assert( GeoIP:new(nmap.fetchfile("nselib/data/GeoLiteCity.dat")), "Cannot read Maxmind database file in 
'nselib/data/'.")
