Followed your instructions above, with small modifications:

(python3) ~/dev/kubric: export CFLAGS="-I/usr/local/include/OpenEXR/ -std=c++11"
(python3) ~/dev/kubric: export LDFLAGS="-L/usr/local/lib"
(python3) ~/dev/kubric: pip install openexr

And by using brew --prefix our two solutions can be merged into one:

(python3) export CFLAGS="-I`brew --prefix`/include/OpenEXR -std=c++11"
(python3) export LDFLAGS="-L`brew --prefix`/lib"
(python3) ~/dev/kubric: pip install --upgrade --force-reinstall openexr

Also, after this succeeds in a virtualenv, the install will NOT fail in the blender REPL.
This is similar to what happened with pybullet (see this issue):

(python3) ~/dev/kubric: bpip install openexr

Posting this for posterity because somehow I keep running into this problem over and over again on different computers. See proposed patch on #43 on the openexrpython main repo.
