Hi. Thanks a lot for that. I will persevere with Homebrew for the time being and fall back to Macports if that road leads to a dead end. If you have time, I’d be very grateful if you could list where your gtk icons reside (eg image-missing.png) in your environment as this will likely help me figure out what has been missed from homebrew (maybe there is an additional package required). Presumably, somebody wrote the rawpedia page and had it working on MacOS with Homebrew, but I’m not sure what version of MacOS was used, or if they (still) frequent this forum. Cheers.
