 Next error I ran into:

 Stop.
 
 Excerpt from stdlib.h of Tru64 UNIX:
 
 #ifdef _BSD
 /*
  * The following prototypes are included to provide support
  * for legacy applications that require BSD 4.3 interfaces.
  *
  * NEW DEVELOPMENT USE OF THESE INTERFACES IS DISCOURAGED!!
  */
 extern int      setenv   __((const char *, const char *, int));
 extern void     unsetenv __((const char *));
 #endif /* _BSD */
 
 So I added -D_BSD in the Makefile and it worked.
 
 Listener.c++ was also affected by pkg/31447
