pkg-static: Unable to access file /usr/ports/graphics/opencv/work/stage/usr/local/lib/python3.9/site-packages/cv2/__init__.py:No such file or directory

Hello.

I'm playing a little bit with sikulix. I'm trying to learn how it works
because I want to automatize the daily tasks of my FreeBSD 13.1-RELEASE.
So,as soon as I have implemented my first "click on the image"
function,I've got the error message that you see below and I don't know how
to fix it :











*[error] RunTime:loadLib: libopencv_java430.so (failed) probably dependent
libs missing: Can't load library:
/root/.Sikulix/SikulixLibs/libopencv_java430.so [error] Save your work,
correct the problem and restart the IDE! [error] see:

At this point I tried to compile opencv from ports enabling JAVA like this :

mario@marietto:/usr/ports/graphics/opencv # make (enabled JAVA)
mario@marietto:/usr/ports/graphics/opencv # make install


but it didn't work :

I suppose that the error depends on the fact that I'm using python 3.8 as
default but it wants python 3.9 ?

mario@marietto:/home/marietto # python --version
Python 3.8.13

What's the right procedure to upgrade it (if I should do this,because I'm
not sure). I tried to remove python38,but I think that it's not the right
choice :

mario@marietto:/home/marietto # pkg remove python38

Checking integrity... done (0 conflicting)
Deinstallation has been requested for the following 580 packages (of 0
packages in the universe)...

but If I don't remove python38 from packages,I can't compile python 3.9
from ports. So,what ?

take also in consideration that I have installed some python packages :

mario@marietto:/home/marietto # pkg remove python39

Checking integrity... done (0 conflicting)
Deinstallation has been requested for the following 6 packages (of 0
packages in the universe):

Installed packages to be REMOVED:
       asciidoc: 10.2.0
       py39-cython: 0.29.30_1
       py39-numpy: 1.22.4_1,1
       py39-setuptools: 62.1.0_1
       python: 3.9_3,2
       python39: 3.9.13

Number of packages to be removed: 6

but I haven't removed them,since I'm not sure if I should do this. I don't
know what to do.
