[Exim] Wierdness with convert4r4?

[root@statler exim-4.00]# ./build-Linux-i386/exim -C /root/exim.conf.4-auto -bt
2002-02-25 13:05:08 Exim configuration error in line 310:
router lookuphost: cannot find router driver "dnslookup"
[root@statler exim-4.00]#

ANd i suppose that should be this part?
lookuphost:
driver = dnslookup
domains = ! +local_domains
ignore_target_hosts = 127.0.0.0/8
transport = remote_smtp
no_more

Im sure i missed something stupid?
