qmail설치하는데요....

centos를 사용하는데요

( ./auto-uid auto_uida `head -1 conf-users`
        &&./auto-uid auto_uidd `head -2 conf-users | tail -1`
        &&./auto-uid auto_uidl `head -3 conf-users | tail -1`
        &&./auto-uid auto_uido `head -4 conf-users | tail -1`
        &&./auto-uid auto_uidp `head -5 conf-users | tail -1`
        &&./auto-uid auto_uidq `head -6 conf-users | tail -1`
        &&./auto-uid auto_uidr `head -7 conf-users | tail -1`
        &&./auto-uid auto_uids `head -8 conf-users | tail -1`
        &&./auto-gid auto_gidq `head -1 conf-groups`
        &&./auto-gid auto_gidn `head -2 conf-groups | tail -1`
        ) > auto_uids.c.tmp && mv auto_uids.c.tmp auto_uids.c
fatal: unable to find user alias
make: *** [auto_uids.c] ?ㅻ쪟 111
