GPG 1.2.0 is installed on my computer with Linux 2.4.18-10. When starting gpg I get: gpg: WARNING: using insecure memory! I have tried to setuid(root) for gpg with the command: chmod a+s gpg. The directory reads: -rws--x--x 1 root root 619833 Feb 22 2002 /usr/bin/gpg What else needs to be done to setuid for root?
