I see this ~every time a new Rivet commit happens, as the Hudson build 
system fails yet again to build Rivet on our test 64 bit system. I've 
not had time to chase this down, but I think it relates to different 
bits of the code having been built with different versions of glibc 
(i.e. different and binary-incompatible compiler versions.) I'm not sure 
why this happens, but SL5 is notably a complete mess when it comes to 
compilers...

So *please* have a look into getting this working, and if you succeed, 
let me know how!
