-------------------------------------
> Could the issue be that Arrow DLLs and Arrow Python (PyArrow C++) DLL are in
> a different location?
Yes, it sounds like the new location of the Arrow Python DLL is not taken into
account (curious that it's still found with the ENABLE-stuff).
In any case, from the POV of conda-forge (i.e. when we get around to packaging
the next released version), this would probably get installed somewhere in
{{site-packages/arrow/...}}. I think it might be best to open a PR to the
arrow-cpp-feedstock that points to the current master here (use {{git_url:}}
etc., I can help if necessary), and we can figure out what needs to be done
(either on the build script side or through patches) so that this runs through.

> Key: ARROW-17771
> URL: https://issues.apache.org/jira/browse/ARROW-17771
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Reporter: Alenka Frim
> Priority: Critical
> Fix For: 10.0.0

>
> It seems that after the Python refactoring PR
> [https://github.com/apache/arrow/pull/13311] Python is unable to find
> {{arrow_python}} even though the library it is imported into the correct
> directory.
> Currently this issue is fixed with setting an additional environment variable:
> {code:}
> CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1
> {code}
> We need to investigate further why this error is happening after the
> [refactoring|https://github.com/apache/arrow/pull/13311] and make sure Python
> is able to find the libraries on Windows without the additional env vars
> being specified.
