in reply to signature test failing
As asarih said, it looks like your ~root/.gnupg/options file is causing trouble. This is causing the "make test" portion of the build fail, which in turn stops the build process. You could try moving the options file out of the way, or editing it to remove/fix the offending lines.
As for your question about cut/paste, try selecting the text you want to paste, then using the middle mouse button to paste. Whenever you select anything, it automatically gets copied. If you only have two buttons, try pressing them both at once (though that could require some setup).
