I installed mailman with a .rpm file on my RedHat 6.1 system. All went well! The list was working fine and it still working. The thing is that now that I want to use the web admin page I get this.

Failure to exec script. WANTED gid 99, GOT gid 502. (Reconfigure to take 502?)

I didn;t get this message before, till now!.. Any ideas on how to fix it short of recompiling mailman? Does anybody know why this happened?
