The copyright notice and the permission notice must appear not only in the code, but also in the supporting documentation (help pages, GIMP manual, whatever). This extends to any derivative works, so this is not compatible with the GPL because anyone re-using this code for any purpose would be required to add these notices in the code and in the documentation. The GPL does not allow that kind of restrictions: "You may not impose any further restrictions on the recipients' exercise of the rights granted herein." Another problem is that the GIMP (the whole package, not only the core) is usually advertised as being released under the GPL (or GPL + LGPL). This is what is mentioned on our home page (www.gimp.org) and this is what appears in most binary distributions. This is stated for example in gimp.spec.in, which creates gimp.spec for RPM distros. The GPL cannot be applied to the whole package, because of the problems mentioned above. So we have to change the license for the source tarball and try to inform those who build binary packages, or stop distributing the files that are not GPL-compatible.
