Yep, there it is... you need to tell bind the ordinal positions of each argument to bind to. Just rewrite the line that constructs bind something like this:
bf = boost::bind(&MyClass::MyMember,&mcl, _1, _2, _3);
...and it should work.
Yes. bind() requires that you supply exactly the number of arguments that is required by the function (object.) http://www.boost.org/libs/bind/bind.html#err_num_args
