[Mailman-Users] wrapper

[DouGy]

hey, I've just setup mailman on my system, everything seems to work... But
when someone posts to the list, maillogs show the mail getting sent the the
wrapper script, and nothing gets sent out.. When I run the wrapper script
from the shell I get:
--------------------------------------------------------
[mailman at omega mail]$ ./wrapper
Usage: ./wrapper program [args...]
[mailman at omega mail]$ ./wrapper post
Failure to exec script. WANTED gid 12, GOT gid 65534.  (Reconfigure to take
65534?)[mailman at omega mail]$
--------------------------------------------------------

any ideas? thanks...
