[Exim] Mailman Errors

Ok. I'm a bit confused now. I thought my system was working correctly now.
But it was only working for users who DO have a Procmail setup
(.procmailrc). For the others, it seems to be trying to run something with
Mailman. Here's a log example:

2002-11-04 12:19:28 188loD-0001ap-00 == hrcg@???
R=list_director defer (-1): failed to expand "/var/mailman/lists/${lc" for
require_files: "${lc" is not a known operator (or a } is missing in a
variable reference)

I'm not sure what to make out of this. Here's the mailman directors
list_owner_director:
#!!# suffix renamed local_part_suffix
driver = redirect
allow_defer
allow_fail
data = "${lc:$local_part}-admin@${domain}"
local_part_suffix = "-owner"
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
retry_use_local_part

owner_list_director:
#!!# prefix renamed local_part_prefix
driver = redirect
allow_defer
allow_fail
data = "${lc:$local_part}-admin@${domain}"
local_part_prefix = "owner-"
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
retry_use_local_part

##
## Next 3 directors direct admin, request and list mail to the appropriate
## transport. List existence is checked as above.

list_admin_director:
#!!# suffix renamed local_part_suffix
driver = accept
local_part_suffix = -admin
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
retry_use_local_part
transport = list_admin_transport

list_request_director:
#!!# suffix renamed local_part_suffix
driver = accept
local_part_suffix = -request
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
retry_use_local_part
transport = list_request_transport

list_director:
driver = accept
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
retry_use_local_part
transport = list_transport

Anyone know what to make of this one?
