I'm using git.  Maybe this output will tell you what I'm using:

Made that change with the result shown in the attachment.

The error about missing unique_ptr is surprising.
I added an #include <memory> near the top of demangle.cpp and that 
solved the problem; however, now getting other errors:

/home/evansl/prog_dev/boost/boost-modular/modular-boost/sandbox/rw/sandbox/boost.actor.dir/boost.actor/src/get_root_uuid.cpp:79:10: 
fatal error:
       'boost/actor/detail/algorithm.hpp' file not found
#include "boost/actor/detail/algorithm.hpp"
          ^
1 error generated.

What should be done about this problem?
