I was having data corruption problems on my internal HD. ¬†Thought I’d reinstall Lion before thinking of new HD. That problem was solved.

Being beyond reach of Wi-Fi, I thought to create a bootable external HD as insurance.

    When I attempted installation, I double-clicked OSinstall.mpkg. Not sure what it means to say Lion couldn't find it.

    Checked out the MacWorld reference. I've never seen Terminal before, I know nothing of UNIX. The command provided looks, to a novice like me, like it's installing Snow Leopard from a DVD. That's a cat of a different stripe. 

    It's not my style to take such a bold step, knowing so little.
    It might be more prudent to outlay the shekes for the Lion thumb drive and install from there.
    I wish I'd done that in the first place.
