Comment (by iqgrande):

 My system has macOS version 10.13.3 and MacPorts version 2.4.2. I hope
 this helps. Also, I forgot to add this to the initial submission, but my
 build does have some variants, i.e., I currently have "LyX
 @2.2.3_4+python27+qt4" installed. I did not choose any of those
 variants... those are what was automatically selected. If I should
 uninstall and then reinstall with a different set, then please let me
 know.
