The really odd thing is that getgid is apparently returning ~0 (gid's 
are unsigned, but the error message prints it as an int, hence the -1). 
I just looked at my groups and the only group with a large number is 
nfsnobody. Are you trying to run this across NFS? If so I'm guessing 
your mount point is not correct because if I recall correctly NFS mount 
points need special flags added to allow execute permissions to pass 
through. I would check that first. If you're not on NFS and/or NFS mount 
point is correctly configured then I would check the following:

Are all the scripts in /usr/lib/mailman/cgi-bin/ owned by root in the 
group mailman with the group sticky bit set (the 7th letter printed out 
by ls -l)

here is an example:
-rwxr-sr-x  1 root mailman 17079 Feb 15 11:21 admin*

What is the contents of your /etc/httpd/conf.d/mailman.conf file? The 
cgi script should look like this:

ScriptAlias /mailman/ /usr/lib/mailman/cgi-bin/
<Directory /usr/lib/mailman/cgi-bin/>
     AllowOverride None
     Options ExecCGI
     Order allow,deny
     Allow from all
</Directory>
