#62891: OpenColorIO binary package — yaml-cpp missing symbol

Component:  ports      |    Version:  2.6.4

-----------------------+-------------------------
 I found while macports was trying to rebuild blender (because it found a
 link error) that the binary package of OpenColorIO contains a
 libOpenColorIO.dylib which references an undefined symbol in libyaml-cpp
 (apologies, I no longer have the log file).

 I rebuilt the OpenColorIO package from source (using `port -s`) locally,
 and now blender can be built and linked (and run, after I gave it acces to
 the whole drive!) fine, so it looks like just a question of rebuilding the
 binary OpenColorIO package against current yaml-cpp, and all will be well.

 Seems very similar to this bug (yaml-cpp ABI change) though not sure it's
 identical. https://bugzilla.redhat.com/show_bug.cgi?id=1773331

 Let me know if any more info required of course, I can investigate
 further.
