The project suggests it’s under a BSD license, but the code itself is a mire of confusion, citing that license (by URL), and an “all rights reserved” copyright statement underneath. Since the BSD license grant is for “use of the Lemur Toolkit…” I don’t think we can reasonably assume that the individual code is actually licensed appropriately for us to use.

Our general attitude, based on past experiences with “foreign” code, is that unless you’ve written it, it’s difficult for us to accept it.
