Um.  This license is clearly a derived work of the GNU GPL.  Was permission
obtained from the FSF?

The intent of this is clear enough: the requirements apply only to the library
as modified, kind of like the LGPL.  But I fear a court would construe
"identifiable portion of the derivative work that is derived from the licensed
software" as meaning any derived work whatever.

Some nailing-down clauses would be useful.
