----------------------------+--------------------
 I am trying to upgrade ports on my Mac OSX Sierra. I have upgraded them
 all. But now when I run my opencv @3.4.8_0+python37 (active) scripts, I am
 getting the following errors and do not know how to resolve.

 Symbol not found: _av_dict_parse_string

 The terminal listing is as follows:


 {{{
 python3.7 python_fit_ellipse.py

 I have the following installed (I was also trying to upgrade to python39
 and opencv3 - don't know if this causes conflicts):


 {{{
 opencv @3.4.3_1+python37
 opencv @3.4.8_0+python37 (active)
 opencv3 @3.4.14_0
 python37 @3.7.5_1
 python37 @3.7.11_0 (active)
 python38 @3.8.11_0 (active)
 python39 @3.9.6_0 (active)

 }}}


 Help would be appreciated.
