That's obviously true. To date, it seems nobody has figured out how to build Sage with SE Linux fully enabled. If somebody did, we wouldn't be having this discussion. > I assume that needs root access, which means one > would need to be root to install Sage on Fedora - not a great idea. It's not an "idea". It's an unfortunate fact until somebody rewrites PARI (etc.) so that they can be built *and* used with SE Linux fully enabled.
