I read http://code.google.com/p/yaml-cpp/issues/detail?id=68 as
saying that a change is needed in the code rather than just the yaml-cpp
build commands. The requested solution is to comment out the two lines 
that attempt to use the stream... so I think the proper solution *is* to 
add the #include <iostream>. Could you do that? Thanks :)

I don't know why this fix was apparently made back in mid-2010 and we 
still have the problem with our bundled version of yaml-cpp. Oh well, 
hopefully next time I update the YAML parser we won't have to repatch 
like this.
