Dear Sir/Madam I followed the instructions on mailman page to install mailman 2.0.5 . Configure and make run properly, but I failed at the stage of checking the installation. My system is Red Hat 6.2 and I'm running Python 1.5.2 I've downloaded mailman-2.0.5.src.rpm and after applying the patch I compiled it. Here are my configure options: ./configure --with-mail-gid=mail --with-cgi-gid=nobody --with-username=mailman --with-groupname=mailman [eliminating the last 2 options had no effect] after make install I went to /home/mailman and.... [root@sharif mailman]# bin/check_perms Traceback (innermost last): File "bin/check_perms", line 50, in ? MAILMAN_GRPNAME = grp.getgrgid(MAILMAN_GID)[0] TypeError: illegal argument type for built-in operation I shall be obliged if you help me on this. Thank you in advance. /* Reza Mahjourian Science and Arts Foundation */ ------------------------------------------------------ Mailman-Users maillist - [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-users
