OK. I believe that I've fixed this now. Can you verify that when you run cmake 
again on this system, that at the bottom (~4 lines from the end) it says 
"Disabling dynamic loading of plugins from the input file" or similar, and 
that it also doesn't compile the offending line in main.cc any more?

This is indeed good news. Want to post your results here on the mailing list?
