Comment (by mascguy):

 Replying to [comment:6 JGoldstone]:
 > Discounting release candidate tags, and 2.x back port releases after we
 moved on to 3.x, the MacPorts port of OpenEXR is at least 25 versions
 behind the current release. Our installation instructions for macOS now
 explicitly recommend Homebrew; see
 https://github.com/AcademySoftwareFoundation/openexr/pull/1382/files.

 Back in October 2022, I was working on adding a new port - `openexr3` -
 which is segregated from `openexr`. That will allow v2.x and v3.x to
 coexist, avoiding the issues associated with any potential
 incompatibilities, etc. (I had to temporarily step away from MacPorts due
 to personal and professional obligations, but hopefully those are now
 behind me.)

 So with any luck, I'll be able to tackle this over the next few weeks.
