How was the OSX build actually built? Was it actually built on the v0.96.1 tag or not? I ask because one commit after the v0.96.1 tag on the master branch, there is a "Fix OSX build" commit. Was the OSX build actually done on that separate commit?
Yes. It wouldn't build with the 0.96.1 tag (oversight by goatpig), so the fix from testing was copied over. That fixed everything, although the build process is broken again due to the libpng library version in the script being unavailable now. (Sourceforge just deleted that version.) I'll PR a new script in a bit.
fix, things build successfully on macOS! Feel free to merge this into master, goatpig.
