Just tried to run a mididing [sic?] with Boost 1.60.  Using the latest git of mididings.  Got this:

TypeError: No to_python (by-value) converter found for C++ type: boost::shared_ptr<mididings::backend::BackendBase>

I found many similar reports with other tools, all referencing Boost 1.60, all talking about reverts to Boost 1.5* as the solution.  Anyone have other ideas?  I'd rather not revert Boost if I don't have to do so.
