Nothing unusual about that: you have two different shared_ptr's visible in 
scope: boost::shared_ptr and std::tr1::shared_ptr.  You need to decide which 
you intend to use and either prefix all shared_ptr usages with the 
appropriate qualifiers, or else just take care to only import the one 
shared_ptr in the first place.

HTH, John.
