Additional info:
-----------------
I have posted this on the cmake mailing list and, as yet, have not gotten a reply; see
    http://www.cmake.org/pipermail/cmake/2013-January/053213.html

Perhaps upgrading to cmake 2.8 as suggested by
    https://bugzilla.redhat.com/show_bug.cgi?id=606892
would solve this problem (since that is what is running on Fedora 17)

This is causing the el6 cppad build to fail. A copy of the attached script can be found at
