Yeah, by now there are lots of useful blogs from various projects figuring out that you can use the install_name_tool to adjust the paths it uses to be absolute or relative to certain magic words, like @executable_path/../lib/blah.dylib, which is tempting, but... realistically, for serious hacking on a Mac, SIP is so annoying that it isn't the only reason you'll want to turn it off: it stops dtrace/dtruss/... from working, and somehow prevents debuggers from working when you've ssh'd in from a remote machine with a proper keyboard, and probably more things that I'm forgetting. I wish I could find the Xnu source that shows exactly how and when the environment is suppressed in this way to understand better, but it doesn't jump out of Apple's github; maybe it's hiding in closed source machinery...
