So on the jenkins master we see the following build error when
building with the bundled boost.

cmake version 2.8.12.2
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-11)

What should we do, except probably consider upgrading cmake and gcc?

Hi,

The Boost build knows on its own that it needs -fPIC -- except if you
link statically, which has its own issues.
