>Description:
Installing security/gnupg on Slackware 10.2, I faced the "gpg: Warning: using insecure memory!" bug (http://www.gnupg.org/documentation/faqs.html#q6.1).
>How-To-Repeat:
Install security/gnupg (gnupg-1.4.2) on Linux (2.4.31, slackware 10.2).
Use it.
See it complain.
>Fix:
# ll /usr/pkg/bin/gpg
-r-xr-xr-x  1 root root 772K 2005-10-10 22:07 /usr/pkg/bin/gpg*

# sudo chmod +s /usr/pkg/bin/gpg

# ll /usr/pkg/bin/gpg
-r-sr-sr-x  1 root root 772K 2005-10-10 22:07 /usr/pkg/bin/gpg*

Now it works OK.
PS: I only use it to sign my mail. I didn't check encryption.
