Yeah, we are aware of it, but it is license incompatible. If you look
at http://www.cgal.org/license.html you will see that the code is dual
licensed. It is available under a mix of LGPL V2.1 or QPL depending on
the module. The more interesting modules are all under the QPL which
is GPL incompatible - see
http://www.gnu.org/philosophy/license-list.html

You could make an optional spkg, but it could not be shipped in
standard Sage and binaries.
