Python 3.10 wheels broken?

On Python 3.10 I get the following error when importing rtree.index:
from rtree import index
File "/home/dianela/.pyenv/versions/3.10.2/lib/python3.10/site-packages/rtree/__init__.py", line 9, in <module>

The wheels work fine for Python 3.9. The installed file is Rtree-0.9.7-cp310-cp310-linux_x86_64.whl

Maybe it's a defunct product of a local build pip ran from the 0.9.7 tarball since there are no 3.10 wheels on PyPI? Should we rerun the CI workflow with 3.10 enabled?

@DianelaOB your issue can be fixed by installing libspatialindex in a manner that CTypes can find it; for example by installing it through your distribution's package manager:
# Ubuntu/Debian example
sudo apt-get update; sudo apt-get install -y libspatialindex-dev
