[cctbxbb] Boost Python 1.56

[Charles Ballard]

FYI,  we (CCP4) have been using 1.56 for building cctbx/phaser/dials for the last while with no issues.  Don't know about 1.60, but 1.59 causes issues with the boost python make_getter and make_setter (initialisation of none const reference if the passed type is a temporary).

I need the function boost::thread::physical_concurrency which returns the number of physical cores on the machine, as opposed to virtual cores when hyperthreading is enabled (which it is by default on any Intel machine). That function is not available in Boost 1.55 which is the version currently used in the nightly tests: it appeared in 1.56.
