<p class="MsoNormal">You are the third person to report this problem. The first person said that what worked for him was to upgrade his MacPort installation. I'm waiting to hear back from the second person as to whether this solution works for him as well.<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>

<p class="MsoNormal">I think the issue is that we used the HPC GNU compilers to build NCL, and if you have the MacPort version of the compilers, then this missing symbol shows up if your MacPorts is old.<u></u><u></u></p>

<p class="MsoNormal">Have you updated MacPorts since upgrading to Sierra?<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">The other possible solution is to download the HPC version of the GNU compilers, which will get installed to /usr/local and hence won't overwrite your MacPorts version that's in /opt/local. Follow this link for more details:<u></u><u></u></p>
