bluetooth 20030604 and 5.1 release

[User Toyboy]

Hello, I downloaded the latest bluetooth stack from 20030604 and I am running 5.1 release which was also tagged on 20030604 and I followed the steps to compile bluetooth  which was "make depend && make && make install && make cleandir" in src/usr.bin/bluetooth/ but it fails at make with:
===> bthost
Warning: Object directory not changed from original /root/sandbox/2003-06-04/src/usr.bin/bluetooth/bthost

This is my first time installing the bluetooth stack and so I was wondering if anyone could help me solve my probelm.  Is there over things that I need to get this to work?  Do you guys have any suggestions?  thnaks for your time.
