[atrpms] gnupg and secret key import/export

Hi!

gnupg-1.4.1-0_25.rhfc3.at seems to be compiled with ENABLE_SELINUX_HACKS, and 
that disables export and import of secret keys *completely* and without a 
notice that this is due to a compile-time option, and not due to user's 
misunderstanding of the man page or gpg's --help text.

Well, this is not a bug, but somewhat annoying. The --export-secret-keys cmd 
could be more verbose on why it "isn't allowed to export secret keys" and the 
same holds for the --import command.

But the main question is: how would I get a secret key, that was created on 
one machine, merged into my secret keyring on another machine?
