Thanks jan - you were right that the difference between the keys was not 
causing the problem.  For future readers, the way to do what i was 
trying to achieve is simple and obvious:

pkey=OpenSSL::PKey::RSA.new(Base64.decode64(userPublicKey))
  if ( pkey.verify( OpenSSL::Digest::SHA512.new, 
Base64.decode64(signatureValue), signatureText ))
    puts " OK: Signature OK"
  else
    puts " ERROR: Signature failed"
  end

I think when I first tried this, I didn't decode the signature, then saw 
the difference in the keys and this threw me off track ...
