11561,"Build fails with threading=single,multi",ryandesign@…,Vladimir Prus,"Hello, I'm the maintainer of boost in the !MacPorts package management system. We just updated our boost to 1.59.0, after which we got a [https://trac.macports.org/ticket/48614 report] that the build fails if `threading=single,multi` is used. The error is:

{{{
error: Name clash for '<pstage/lib>libboost_atomic-mt.dylib'
error: 
error: Tried to build the target twice, with property sets having 
error: these incompatible properties:
error: 
error:     -  none
error:     -  <dll-path>/opt/local/bin
error: 
error: Please make sure to have consistent requirements for these 
error: properties everywhere in your project, especially for install
error: targets.
}}}

This used to work with 1.58.0 and earlier. Our default is `threading=multi` which still works fine with 1.59.0.",Bugs,new,To Be Determined,build,Boost 1.59.0,Problem,,,
