In effect i looked inside some sp file and i have seen that it need leftdowntown. But for me some sp file on windows failed to compile. I am installing a linux server right now to do some test on a home linux server to upload later in the rented server but i am not expert on linux and i have some issue with firewall. For now i use another plugins that it does something similar. Not perfect but it is the best i found. http://forums.alliedmods.net/showthread.php?t=190009
