Thanks @lovelxc!

I had the same issue with an old version of bustub (fc57dab). Similar issue.

The following steps worked on my side (could be more concise but regardless):

1. brew install binutils
2. brew edit binutils
3. In the binutils.rb file that just opened, on line 24, add the following option "--enable-install-libiberty",. Save this file somewhere (e.g., your desktop).
4. brew reinstall -s ~/Desktop/binutils.rb. Confirm that the option is included when it runs the configure (./configure --enable-install-libiberty ...).
5. (Unsure if necessary) As prompted by brew, adjust your PATH.
6. Do a fresh build. E.g., remove build directory and follow steps under "To build the system from the commandline..." here.
