Can't launch plone site after fresh install of Plone 5.0.5 on OSX 10.11.6

After fresh install of Plone 5.0.5 on OS X 10.11.6 I can create a new site using the provided url. However when I try to access the new site with browser Plone exists with the following .... Any assistance on what I may be doing wrong here would be much appreciated....

This is a very uncommon error (never seen in 25 years of using Python).

Is this error persistent and reproducible or is this a one-time error you have seen?

Likely a internal memory corruption error in the underlaying malloc() implementation for whatever reason.
If it is a singular error that does not come back then don't care about it.

RE: This is a very uncommon error (never seen in 25 years of using Python)._
Oh lucky me.... ;-(

RE: Is this error persistent and reproducible or is this a one-time error you have seen?

This happens every time.

The steps are as follows... The "Plone is up and running" page displays successfully when I access localhost:8080. However, when I click the link to access a specific plone site, plone exits as shown in the initial post.

Perhaps an issue with the Python shipped with the universal installer.
@smcmahon might know...
Usually I am compiling Python myself...never used the universal installer.

Apparently was an issue with my MacPorts installation which had not been updated for the latest OSX.

To resolve the issue I followed instructions on Migrating a MacPorts Installation located at: https://trac.macports.org/wiki/Migration
