Sorry, that was a typo in my message here. In the Jamroot file, there was a
space.

You might very well be correct in this but it works fine with and without
the colon (some leniency in bjam, I assume).

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. 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.

But I have now found another solution: I have put 'export
BOOSTROOT="/usr/local/include/boost-1_39" (or the corresponding path on
different machines) in my .bashrc file and ' <include>$BOOSTROOT'. They
Jamroot file can now be the same on all machines.
