Steps to Reproduce:
$ rpm -q --qf '%{LICENSE}\n' librpm
GPL
$
Actual Results:  
rpm-4_0-4.0.4/COPYING:
The entire code base may be distributed under the terms of the GNU General
Public License (GPL), which appears immediately below.  Alternatively,
all of the source code in the lib subdirectory of the RPM source code
distribution as well as any code derived from that code may instead be
distributed under the GNU Library General Public License (LGPL), at the
choice of the distributor. The complete text of the LGPL appears
at the bottom of this file.
This alternatively is allowed to enable applications to be linked against
the RPM library (commonly called librpm) without forcing such applications
to be distributed under the GPL.
