I mean I had to manually patch the rpaths of macos binaries distributed as an app bundle, because dyld didn't have the relative location of the shared libs in the app bundle in its search path. Not a huge deal, since patching rpaths was also part of the other Unix pipelines, the reasoning was just different. Patching rpaths on other platforms was because we were distributing dependencies in the base directory of the application, which isn't the standard way to do things. On mac, it was because the dynamic linker wasn't aware of app bundle structure for some reason, which is a weird disconnect between an OS standard and a basic system component.
