#57562: py-matplotlib-basemap 1.1.0_0 incompatible with matplotlib 3.0.1_0
------------------------+-----------------------------------
 Reporter:  EJFielding  |      Owner:  (none)
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.5.4
 Keywords:              |       Port:  py-matplotlib-basemap
------------------------+-----------------------------------
 The present version of matplotlib-basemap is trying to import something
 that seems to be no longer present in matplotlib. These are the versions
 that I have installed:
   {{{
 py36-matplotlib-basemap @1.1.0_0
 py36-matplotlib @3.0.1_0+cairo+webagg (active)
 }}}

 This is the last part of my error trace:
 {{{
     import mpl_toolkits.basemap as basemap
   File
 "/opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6
 /site-packages/mpl_toolkits/basemap/__init__.py", line 17, in <module>
     from matplotlib.cbook import is_scalar, dedent
 ImportError: cannot import name 'is_scalar'
 }}}
