https://github.com/ruediger/Boost-Pretty-Printer auto-detection relies on compiling a C++ program using the system's version of boost. The system's version of boost is probably not the same version as the mongodb/mongo version (master is currently 1.79.0) and not all platforms have boost installed.

The newest boost version https://github.com/ruediger/Boost-Pretty-Printer verifies it supports is 1.73.0. However, we mostly rely on this repository for printing boost::optionals which hasn't changed its internal format since then anyway. Specifying boost_version=(1, 73, 0) should therefore be good enough for the Server team's purposes.
