[Mailman-Users] Problem during install

[Webmaster]

I finally got the configure file to run properly. I think it had to do with
the fact that my ftp client decided to transfer it in Binary and not ASCII.
That's the only thing I can think of.
I am now getting this error:
checking permissions on /home/micheal/www/mailman... configure: error:
***** Installation directory /home/micheal/www/mailman is not configured
properly!
***** Set-gid bit must be set for directory: /home/micheal/www/mailman

I'm not totally sure how to fix this. Any suggestions?
