@swatanabe Can you please offer some advice on this one? I hardcode boostcpp.tag here: https://github.com/boostorg/boost_install/blob/develop/boost-install.jam#L314, but the boost_python and boost_numpy libraries use their own local python-tag, which takes the value of <python> into account. I could of course special-case these, but it might be more proper to somehow use the <tag> of the library, instead of hardcoding boostcpp.tag.

Should be fixed in develop.
