Bug 197889: 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'

--- Description ---
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:

http://package18.nyi.freebsd.org/data/93i386-default-PR196712/2015-01-18_16h49m
19s/logs/errors/calligra-2.7.5_14.log

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.)
