 Greetings,

 When I try to use py37-matplotlib @3.1.1_0+cairo+webagg to perform an
 action that requires a triangulation via the Qhull library, it fails with
 the following message:

 {{{ QH6249 qh_lib_check: Incorrect qhull library called.  Size of qhT for
 caller is 2792, but for qhull library is 2896.
 QH6256 qhull internal error (qh_lib_check): Cannot continue due to
 QH6249..  Library 'qhull 7.3.2 (2019.1 2019/06/21)' should use a static
 qhT (e.g., libqhull.so).  It may be out-of-date.  Exit with 49 }}}

 While this appears to happen with any triangulation, it is easily
 reproducible using this example from the Maptlotlib website:
 https://matplotlib.org/3.1.1/gallery/images_contours_and_fields/irregulardatagrid.html
 #sphx-glr-gallery-images-contours-and-fields-irregulardatagrid-py

 The error states that qhull may be out of date, this does not appear to be
 the case.

 This is new behavior, but I cannot pinpoint when it started happening (I
 upgraded outdated ports last week, but haven't attempted a triangulation
 recently).

 I am currently listing this as an issue with Qhull, but this could be a
 problem with matplotlib or scipy.  My apologies as I'm not entirely sure
 where to direct this request.
