I just took a look at http://tinyurl.com/9y4td and it looks to me like  
an error in the date_time library.  The compile time error is:

Error : illegal operands 'std::basic_istringstream<char,  
std::char_traits<char>, std::allocator<char>>' >>  
'boost::date_time::date_duration<boost::date_time:: 
duration_traits_adapted>'

And I can't find an operator >> (istream&, date_duration&) in namespace  
boost::date_time, though I can find one in boost::gregorian.  I suspect  
that this would rightly cause the error.

I haven't looked at any of the other failures.
