I'd be shocked if these issues were OS specific, but anything's
possible.  Also, if you look at their tracker there's no shortage of
worrisome problems.

Nope, doesn't compile out-of-the-box.  I'm back to the latest.

Huh.  Nice; uses Boost, and the code doesn't look nearly as awful as
that other library.  I can't find an API reference, but I guess I could
start from the assumption that everything has the same name in both
