Does it work with Boost.Phoenix?  Boost.Phoenix includes the
functionality of both and a great deal more.  I have not tried this,
but curious if it works for you:

#include <boost/spirit/home/phoenix/bind/bind_function.hpp>
#include <boost/lambda/bind.hpp>
#include <boost/bind.hpp>

struct Functor
{
       void operator()() const
       {}
       template<class T> void func(T t)
       {}
};

int main()
{
       Functor f;
       boost::phoenix::bind(&Functor::func<Functor>, &f, f); // Does
this compile?
       boost::lambda::bind(&Functor::func<Functor>, &f, f); // doesn't compile
       boost::bind(&Functor::func<Functor>, &f, f); // compiles well
}
