Has anyone seen an error like this?

SpecialDate is a user-defined type, however, I'm getting the following:

boost/test/test_tools.hpp(326) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'const  is a user-defined type, however, I'm getting the following:
' (or there is no acceptable conversion)

Thanks in Advance,
