Yes, this presumption is right. After 'pkg delete -f libc++-200683
libcxxrt-20131225_1' I am able to use rawtherapee furthermore. So ports
like RawTherapee would also work, when devel/libc++ and devel/libcxxrt
would be deinstalled right after successfull installation of the port.
My problem is more the other side around: Why do ports like e.g.
graphics/darktable pick up the headers from devel/libc++ instead of the
base ones? In darktable there is no devel/libc++ dependency specified.
Installing graphics/darktable, while devel/libc++ is already installed,
creates a dependency.
This will jumble up the dependency list in ports/packages and should not
happen. Only ports with a declared dependency on devel/libc++ should use
>> #pkg info -r libc++-200683
