--------------------------+-------------------------------------------------
 As of Boost 1.37 or so (a long time ago), Boost.Math became a header-only
 library.  Most distributions still provide a libboost-math-c99.so, but
 some (RHEL5 and RHEL6 base packages -- not ATrpms or other third-party
 repositories) do not, because it's header-only.  Some investigation needs
 to happen here to figure out how to handle this:

 1. Why do most repositories still provide a shared library for Boost.Math
 if it is header-only?  What's in it?

 2. CMake should look for the shared library; if it does not find it, it
 should search for the Boost.Math headers.  If those aren't found, the
 configuration should fail; otherwise, it should be successful.

 Currently, a build on RHEL5 or RHEL6 without third-party repositories
 fails because there is no shared library for Boost.Math.
