The problem is that OpenVRML 0.16.x's parser doesn't make the DEF name
available for usage in a ROUTE until the end of the node body.  In your
file, the problem ROUTE occurs inside the body of the node Teapot01.

I tried your file in trunk OpenVRML and it works there.  I suspect this
got fixed in 0.17.0 when the Antlr-based parser was replaced with the
current Spirit-based one.
