Hmm I built it on windows (had to put in a fair number of changes) and tried to convert pknowledge.s3d and got out a .ter file but it seems to have major problems. My renderer program seems to be getting fairly random numbers and crashes when it tries to allocate memory for -200000 vertexes. 
 
May be a problem with the conversion I had to do to make it run on windows. I'll have another look later when I'm home from work.
