The L of LGPL stands for "lesser".  I'm not sure what the difference is 
between the LGPL license and the GPL license, but apparently they are 
different:

The "lesser" license is a successor of the "library" license:

http://www.gnu.org/licenses/old-licenses/lgpl-2.1.html

I read the following last night, and that is what prompts me to ask if 
due consideration was given:

"This license, the Lesser General Public License, applies to some 
specially designated software packages--typically libraries--of the Free 
Software Foundation and other authors who decide to use it. You can use 
it too, but we suggest you first think carefully about whether this 
license or the ordinary General Public License is the better strategy to 
use in any particular case, based on the explanations below."
