Nmap is completely self contained. It doesn't depend on anything other than it's own built-in code. If you are having trouble, there are a lot of things that can effect it. To have access to all of the features, you need to be logged in as root. Also, if you are scanning a system that is inside of the network, and all of the traffic is going through a switch, the switch may be effecting it. Try slowing down the speed of the scan, and randomizing the port order. Also, shut off ICMP ping, tcp ping, and "ping host before scanning". It is possible that a switch or firewall will block these things. If you are truing to scan a system ouside of the firewall, then it is most likly being blocked.
