Comment (by dershow):

 I see the error a little differently, but I suspect that it's the same
 issue.

 If I do:

 {{{
 from matplotlib.backends.backend_pdf import PdfPages
 }}}


 I get this error:
 {{{
 /opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9
 /site-packages/matplotlib/backends/_backend_pdf_ps.py in <module>
       6 import functools
       7
 ----> 8 from fontTools import subset
       9
      10 import matplotlib as mpl

 ModuleNotFoundError: No module named 'fontTools'

 }}}
