I'm not sure what the issue here is. Please send me line 169 of
build/doc/uguide/CMakeFiles/arts_developer-stage1.dir/build.make to further
look into this.

This seems a bit suspicious to me. Did you really install these packages AFTER
compiling ARTS? Since cmake does check for these packages during configuration,
you should not have been able to compile ARTS if these were not installed.
Which makes me wonder if you have two different Python versions installed,
which might also lead to the error you're seeing below.

The import error indicates that Python cannot find the arts cpython library.
Please double check that this file exists:
/users/michael/ARTS/arts-2.5/build/python/pyarts/arts.cpython-39-x86_64-linux-gnu.so
If the filename does not contain "-39-" but "-38-" or "-310-", that would
indicate that during cmake configuration the wrong Python version was used.
Double-check the output of cmake during configuration to make sure that it
finds the same Python version which you are using later to import pyarts into.
The output during configuration looks like this:
-- Found Python3: YOURPYTHONPATH/bin/python3.X (found version "3.X.X") found
components: Interpreter Development.Module
