Thanks for your carefulness.

On the website they explain it as follows:  A part of the code is "LGPL"
(no version specified) and a part is MIT.  The most "restrictive" (as
they call it), determines the license of the whole package (and thus
it's "LGPL").

I actually couldn't find which version of the LGPL, so I assumed the
latest variant.  The COPYING file does mention version 2.1 or later.
The same file also reassures that the entirety of the package is
governed by the LGPL (v2.1+):

I attached a new patch.
