Try putting a space between the colon and "<include>/usr/local/...".
Sorry, that was a typo in my message here. In the Jamroot file, there was a
space.

I don't think this is right. Per:
http://www.boost.org/boost-build2/doc/html/bbv2/advanced/targets.html
the syntax is:
rule-name (
    main-target-name :
    sources + :
    requirements * :
    default-build * :
    usage-requirements * )
So you should have:
exe myname
    : myname.cpp
    : <include>.
      <include>/usr/local/include/boost-1_39/
    ;
You might very well be correct in this but it works fine with and without
the colon (some leniency in bjam, I assume).

You need to use project requirements in user-config.jam, see:
http://www.boost.org/boost-build2/doc/html/bbv2/advanced/projects.html
For example:
project user-config : requirements <include>/usr/local/include/boost-1_39
;
Maybe we are talking about different user-config.jam files. I have put the
entry 'using darwin ;' into the user-config.jam file sitting in
/usr/share/boost-build as it is a project-independent settings (as would be
the location of the libraries). I would not want to put any project-specific
settings in this file.
In that case, you can also put file named project-config.jam in the root of your
project and *do not* add it to any version control.
...
But without fully understanding it, I put your 
above-mentioned line into the user-config.jam file, it does not work (it
complains about not finding the boost library, or more specifically the
specific file I included in the header of my .cpp file). Trying out:
project myprojectname : requirements <include>/usr/local/include/boost-1_39
;
also does not work.
This is fairly strange -- this functionality is available for years. Please
pass --debug-configuration and note which user-config.jam is being loaded --
maybe you have one in home.
