Solving this will require changing the archive action in the 
tru64cxx65-tools.jam file. The most generic way I can think of is to 
change it to something like so:

actions updated together piecemeal tru64cxx65-Archive-action
{
   rm -f $(<)
   ar r$(ARFLAGS) $(<) $(>)
   for i in "$(<[1]:D)"/cxx_repository/* ; do ar r$(ARFLAGS) $(<) $i ; done
}

Tell me what works for you and I'll update the toolset in CVS.
