     Type:  defect       |  Milestone:
 Priority:  Normal       |    Version:  2.3.4
Component:  ports        |       Port:  cmake gnuradio gr-foo gr-ieee802-11
 Keywords:  haspatch     |  gr-ieee802-15-4 volk
-------------------------+-------------------------------------------------
 The cmake, gnuradio, gr-foo, gr-ieee802-11, gr-ieee802-15-4, and volk
 ports include a block of code designed to select the correct compilers for
 code that requires C++11.

 Large amounts of common code should not be copy/pasted; instead a
 portgroup should be created.

 The cxx11 1.0 portgroup already exists to provide this functionality. The
 gnuradio port was not using it, but the others were, conditionally, if
 libc++ is used. The portgroup is designed to be included unconditionally,
 without regard for which C++ library is used, and to provide the user the
 correct advice or behavior in either case. If this portgroup is not
 meeting your needs, please enhance the portgroup or discuss the situation
 on the macports-dev mailing list. Otherwise, just include the portgroup
 and let it do what it's designed to do; see attached patch.
