In the future run in dbg mode before posting bug reports if possible;
in this case it didn't matter, but in general the output is usually

What version of libMesh are you using?  We only got version 4 support
added to libMesh a couple weeks ago:

So if you want to use it you'll need to be using the git master, I
believe.
