The kclient(1m) script from the system/security/kerberos-5 package contains this:

1193    grep=/usr/xpg4/bin/grep
1194
1195    object=$(mktemp -q -t kclient-computer-object.XXXXXX)
1196    if [[ -z $object ]]; then
1197        printf "\\n$(gettext "Can not create temporary file, exiting").\\n
1198" >&2
1199        error_message
1200        fi
1201
1202    grep=/usr/xpg4/bin/grep

...

1429    # RC4 comes next (whether it's better than 1DES or not -- AD prefers it)
1430    if encrypt -l|$grep -q ^arcfour
1431    then
1432        ((val=val+4))
1433        enctypes[${#enctypes[@]}]=arcfour-hmac-md5
1434    else
1435        # Use 1DES ONLY if we don't have arcfour
1436        userAccountControl=$((userAccountControl + 2097152))
1437    fi
1438    if encrypt -l | $grep -q ^des
1439    then
1440        ((val=val+2))
1441        enctypes[${#enctypes[@]}]=des-cbc-md5
1442    fi

There are several issues here:

1. The assignment to grep variable is twice there (lines 1193 and 1202).
2. The only usage of the grep variable is at lines 1430 and 1438, but there is no reason to use /usr/xpg4/bin/grep for this. Any grep available on the system (including /usr/bin/grep or /usr/gnu/bin/grep) should do the job right too.
3. The /usr/xpg4/bin/grep is in system/xopen/xcu4 package, but system/security/kerberos-5 does not depend on it.
