 1. security/tcp_wrappers/ is the logic to determine whether a
    builtin is available, and if so whether it should be used.  In this
    case it checks for the existence of /usr/include/tcpd.h and libwrap in
    the system library paths.
 2. IS_BUILTIN.tcp_wrappers will tell you if a builtin has been detected.
 3. USE_BUILTIN.tcp_wrappers will tell you if the builtin will be used.
 1 and 2 are independent of any settings, 3 can be controlled with
 PREFER_PKGSRC etc.  The likelyhood is that your systems are different, and
 one of them has tcpd.h/libwrap installed and the other does not, but
 IS_BUILTIN will tell for sure.
