How to downgrade command line tools MacOS
<p>I got a dynamic linker error with the <code>__clock_gettime</code> symbol so I did what this post said <a href="https://stackoverflow.com/questions/39302619/missing-symbol-when-installing-ruby-2-3-0-on-os-x-10-11-6-by-rvm">Missing symbol when installing ruby-2.3.0 on OS X 10.11.6 by RVM</a> (i.e. <code>xcode-select --install</code>) and now I am getting loader errors that say that libraries were built for a newer OS version than the one I am currently running on,  I dont want to upgrade my OS to the newer (Sierra) version though, is there a way you can downgrade the command line tools to an older version (10.11?)</p>
