<div>I want to report an apparently smooth upgrade of macports when I upgraded my OS to Sierra from Mavericks.</div>
<div><br>
</div>
<div>I tried to follow the <a href="https://trac.macports.org/wiki/Migration">instructions</a> exactly, and found some minor issues:</div>
<div>1) The lack of a gfortran meant that install errors were found using the restore_ports.tcl script. </div>
<div>2) I manually installed gcc49 which created gfortran (almost).</div>
<div>3) I had to manually softlink the commands “gcc” and “gfortran” to the versions found in /opt/local/bin. Then “gcc" and “gfortran" were on my path. </div>
<div>3) I tested it by installing Atlas first, which worked.</div>
<div>4) The restore_ports.tcl reported the error below. It does not seem to have propagated to anything else. Further testing of the ports will reveal if there are any issues. </div>
<div><br>
</div>
<div>Instructions for installing command line tools of Xcode can be found here: http://railsapps.github.io/xcode-command-line-tools.html. </div>
<div>Just issue the command </div>
<div>xcode-select —install.</div>
<div>
<div>
<div><br>
</div>
<div>Part of the install output:</div>
<div>
<div>---> Cleaning bzip2</div>
<div>---> Fetching distfiles for cctools-headers</div>
<div>---> Verifying checksums for cctools-headers</div>
<div>---> Extracting cctools-headers</div>
<div>---> Configuring cctools-headers</div>
<div>Error: cctools-headers has been replaced by libmacho-headers; please install that instead.</div>
<div>Error: Failed to configure cctools-headers: obsolete port</div>
<div>Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_cctools-headers/cctools-headers/main.log for details.</div>
<div>---> Cleaning cmsvlib</div>
</div>
<div>Etc.</div>

<div>Thanks to the community for an overall smooth and successful process. </div>
