OK, I have it.  Here is a little snippet of usage:

class sum
{
public:
    sum(int base)
        : m_base(base)
    {}

    int add1(int num) const
    {   return m_base + num; }

    int add2(int num1, int num2) const
    {   return m_base + num1 + num2; }

private:
    int m_base;
};

...

boost::function<int(int)> fun1 = bind_mem_fn(&sum::add1, test_sum);
boost::function<int(int, int)> fun2 = bind_mem_fn(&sum::add2, test_sum);

complete example/test file (tested with GCC 4.0.1, using recent svn
boost trunk):

I think you only need the following two files:
http://svn.boost.org/svn/boost/sandbox/SOC/2007/signals/boost/dataflow/utility/bind_mem_fn.hpp
http://svn.boost.org/svn/boost/sandbox/SOC/2007/signals/boost/dataflow/utility/member_function_signature.hpp

I'd appreciate it if you could let me know whether it works for
you/what platform.

Cheers,
