Comment (by EJFielding):

 I don't see anybody listed as maintainer for the py36-matplotlib-basemap,
 so I don't know who to "cc:" on this. The py36-matplotlib port was updated
 to version 3.0.2_0, and the basemap module version 1.1.0 is still
 incompatible. One one of my Macs, I was able to activate the older version
 of py36-matplotlib, but on the other I already ran "port reclaim" and
 deleted it so I can't run my Python code that tries to import the basemap
 module. I tried a quick fix to the
 {{{
 /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6
 /site-packages/mpl_toolkits/basemap/__init__.py
 }}}
 code by deleting the import of "is_scalar", but it then failed further
 down. It seems that the only fix is to update the Basemap code do 1.2.0 or
 later.
