I have a class that provides a shared_ptr number.  At the end of the 
number's life cycle it should be placed back on a list of available 
numbers.  The shared_ptr's custom deleter function looks like what I 
need.  I'm able to get a free function to compile as the deleter just 
fine.  In trying to use a class member function as the custom deleter 
I've run into compile errors.  I'm not sure where I'm going wrong.  I 
know the custom deleter need to be copy constructible and I'm probably 
breaking some assumed requirement.  Any help on what I'm doing wrong 
would be appreciated.

class CTNGenerator {
public:
CTNGenerator(void) {
 m_AvailableCTNs.resize(20);
 unsigned short startValue = 15;
for (ctns::iterator itor = m_AvailableCTNs.begin(); itor != 
m_AvailableCTNs.end(); ++itor) {
   //This compiles fine.
   boost::bind(boost::mem_fun(&CTNGenerator::makeCTNAvailable), this);
   //Placing the call as the custom delete function doesn't compile.
   *itor = bus(new unsigned short(startValue++), 
boost::bind(boost::mem_fun(&CTNGenerator::makeCTNAvailable, this)));
 }
}
Check you parentheses.  The two uses of bind/mem_fun are not the same.
