Ok, I put the message in my project. Here is the output.

505:[mjackson at Thor:Build]$ cmake ../
-- -w
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/mjackson/Workspace/FSTest/ 
Build


Also, I have access to a Linux box with ICPC Version 10.1.008 on it  
and I tried the same thing and it does work on the linux box. So,  
yes, something in my Darwin-icpc is messed up. Just not sure what.
