The existing source includes the logic and routines to support libwrap 
already, specifically in server/libvncserver/sockets.c:

#ifdef USE_LIBWRAP
#include <syslog.h>
#include <tcpd.h>
int allow_severity=LOG_INFO;
int deny_severity=LOG_WARNING;
#endif

...

#ifdef USE_LIBWRAP
     if(!hosts_ctl("vnc",STRING_UNKNOWN,inet_ntoa(addr.sin_addr),
                   STRING_UNKNOWN)) {
         rfbLog("Rejected connection from client %s\n",
                inet_ntoa(addr.sin_addr));
         close(sock);
         return;
     }
#endif

However, I could not find a means within the existing package to trigger 
these blocks without manually including the define in some way.  Once 
USE_LIBWRAP is defined, the support is included in the resultant package.
