Description (last modified by mf2k (Frank Schima))
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 It may be out-of-date.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The error states that qhull may be out of date, this does not appear to be the case.
This is new behavior, but I cannot pinpoint when it started happening (I upgraded outdated ports last week, but haven't attempted a triangulation recently).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.

Thank you- I must have just missed some of these updates as I did an update outdated yesterday before posting this. This morning, both MPL and Numpy are updated and things work.
Thanks; sorry for the poor timing.
