I wouldn't call this politically, but the constants in example.pl are
out of sync in multiple ways. From example.pl:

  # Same as src/include/radiusd.h
  use constant  L_DBG=>   1;
  use constant  L_AUTH=>  2;
  use constant  L_INFO=>  3;
  use constant  L_ERR=>   4;
  use constant  L_PROXY=> 5;
  use constant  L_ACCT=>  6;

The cannot be found in the given file, but the are available in
src/include/log.h:

  typedef enum log_type {
    L_AUTH = 2,   //!< Authentication message.
    L_INFO = 3,   //!< Informational message.
    L_ERR = 4,    //!< Error message.
    L_WARN = 5,   //!< Warning.
    L_PROXY = 6,    //!< Proxy messages
    L_ACCT = 7,   //!< Accounting messages

    L_DBG = 16,   //!< Only displayed when debugging is enabled.
    L_DBG_WARN = 17,  //!< Warning only displayed when debugging is
      enabled.
    L_DBG_ERR = 18,   //!< Error only displayed when debugging is
      enabled.
    L_DBG_WARN_REQ = 19,  //!< Less severe warning only displayed when
      debugging is enabled.
    L_DBG_ERR_REQ = 20  //!< Less severe error only displayed when
      debugging is enabled.
  } log_type_t;
