I think that is an artifact of the same library being installed in two
places.  As far as I understood bapt@ (Cc'd), the idea is that the port
mirrors the c++ library we have in the base system, and both are
compatible, and particularly, they have the same ABI.  Basically we need
the libc++ headers to make use of libc++'s inline namespace so that
rawtherapee references libc++'s symbols (in the std::__1:: namespace)
rather than libstdc++ (in the std:: namespace).

If you are willing to experiment, you should be able to deinstall libc++
now, and both darktable and rawtherapee should continue to work with the
base libc++.
