Indeed, the metadata in the gem is wrong. The information on the license
is a bit sparse. LGPL 2.1 is included in the sources, and there is one
file which references this in the header.

The published gem doesn't come from the original author, so I'm guessing
the default in the gemspec simply wasn't changed.
