Loading scipy.interpolate gives a library error

[ATL-Flaneur (Andreas Yankopolus)]

I'm on MacOS 10.14.2 (18C54) and after first running into this problem did a complete removal of MacPorts, system reboot, reinstall of MacPorts base, and Python reinstall with:

sudo port instal py37-ipython py37-scipy py37-matplotlib py37-pip

Then:

ayank$ ipython3
Python 3.7.2 (default, Dec 30 2018, 08:55:50)
