            Bug ID: 197889
           Summary: editors/calligra fails when default version of GCC is
                    4.9 (or higher): /usr/local/lib/libIlmImf.so:
                    undefined reference to
                    `std::__throw_out_of_range_fmt(char const*,
                    ...)@GLIBCXX_3.4.20'

This is related to PR 196712 and blocks updating the default version of
GCC from 4.8 to 4.9.

Here is a build log, apparently the problem only happens on FreeBSD 9.x,
and not 10.x:

To me it appears the problem is that calligra pulls in graphics/OpenEXR
which uses GCC in some cases, and now clang++ is trying to link bits 
prepared by two different compilers.  (Cf. PR 196853 for another case.)
