The bug was not closed, but I can confirm that this build-dependency is gone from the version of the package in the archive.

This build-dependency is present because of the recommendations on https://wiki.ubuntu.com/cpp-11 about handling of C++11. The C++11 ABI has now stabilized in gcc as of gcc 5; however, before we can switch to gcc 5, we first need to be able to do rebuild tests of the archive against this compiler. To facilitate this, please drop the build-dependency on g++-4.9 from the package in wily. 4.9 will remain the default until all transition issues have been identified, so there is no risk of accidental ABI breakage here anymore.
