The path to kdb5_util has been set to '$kdb5_util_path'.

If this is not where your version of kdb5_util is located, use the
following options to Makefile.PL:

    KDB5_UTIL_PATH=...  To set the directory where kdb5_util is located

For example:

    perl Makefile.PL KDB5_UTIL_PATH=/usr/local/krb5/sbin
