That is not your problem, since you can see in the output that it is 
using Boost from /usr/local/include, not /usr/include (which is where 
the system Boost is stored).

Having said that, you may need to double-check that your library path 
also uses /usr/local/lib before /usr/lib otherwise you may experience 
other problems later on.

Another thing to verify is whether you are compiling your application 
with C++11 or higher options (which the compiler output suggests is the 
case).  If so, you should specify the same options when building Boost.

Otherwise, look closely at 
examples/user_code/openpose_recognition.cpp:867 and see if the code is 
correct.

That is never a good idea.  You can't remove the system Boost libraries 
without removing or rebuilding every other system package that depends 
on it, which will most likely break your system.

You can't.
