Actually its some problem with the code.
Not sure why they didnt sort this out, or havent yet, but this is the offending line in 'portsentry.c' file:
printf ("Copyright 1997-2003 Craig H. Rowland <craigrowland at users dot
sourceforget dot net>\n");
Just this is on 2 lines, you cant have this in c programming so, I just removed the line and it works now, not sure why they havent picked up on this yet but hey!
Might try and find a contact and ask them to do this to allow other users who dont know C very well to work with this.
