[Mailman-Users] CGI error (got gid -1)

Hi all !

I've got a very strange error using mailman...

I compiled the sources specifying the right mail gid (12 for me) and the right cgi gid (99), but

when I create the test list and I try to access the web page, I get this error :

Mailman CGI error!!!

This entry is being stored in your syslog:

Failure to exec script. WANTED gid 99, GOT gid -1.  (Reconfigure to take -1?)

What is this strange gid : -1 ? Is this a bug ? Does anyone know a solution ?

Thank you.

Gan.
