Cannot access file in python "unsafe use of relative rpath"

ROOT
16

Okay so I found on this thread that python quitting is due to conflicting python versions. The same thread recommends sticking with the system build though.

I think this is a legitimate bug related to Apple’s introduction of System Integrity Protection. I was able to fix it using install_name_tool. Unfortunately, there were several such links so it needed to be done multiple times; there’s a suggestion here for doing it automatically, but I just did it manually:

$ install_name_tool -change libXrdUtils.2.dylib /Applications/root_build/lib/libXrdUtils.2.dylib /Applications/root_build/lib/libNetxNG.so

Now I’ve got a new problem:

$ python

Error in <TNetXNGFile::Open>: [FATAL] Auth failed

But it seems unrelated to the original problem in this post, so I will simply start a new thread. Thanks much for taking the time to help, everyone.

By the way, there are WAY too many problems trying to get this installation up and running. I almost regret even trying.
