 Hi,

 This might not be a bug, but since I found no page with a clear statement
 about this, I prefer reporting it anyway, so that at least people facing
 the same issue can find this ticket :)

 Boost cannot be used with _LIBCPP_DEBUG enabled.  I don't know if it would
 be possible for boost to deliver versions of the libraries that would have
 been compiled with it?  Maybe that's exactly why some distros with `-d`
 versions of the libraries?
