Steve, I am still reviewing this, and I need to to a build with non-GPLv3,
since you might have added a dependency with zypper on a GPLv3 item, this
will take me some checking.

You might want to prepare a patch and test with a GPLv2 version of gnupg as
well.  This will not hold up this patch if we know the GPLv2 version is
forth coming.

I'm not sure that a version 1.x of gnupg will give signed repository support.

The zypper package seems to explicitly use gpg2, see log below:

If I get some time later this week I will experiment with a earlier
version of gnupg, though I suspect we might have to create a somewhat
questionable symlink from gpg2 to gpg.  Note that it actually seems to
use *both* gpg2 and gpg!
