Binaries from GPL libraries should *NEVER* be installed on your device unless you know EXACTLY WHAT YOU ARE DOING, and WHY you are doing it.
GPL is the Gnu General Public License.
The GPL license requires any party that is using code covered by such a license to publish the source code for those libraries, including all changes and patches the "publisher" includes or develops themselves.
GPL libraries *never* include the PROPRIETARY code. And in the case of the Elements Play Gen 2, probably 95% of the code is propietary. In the Gen 1's case, 100% of it is proprietery, hence NO GPL code.
