toolkit not being recognised

[tdudgeon]

When installing using PIP I'm getting an error saying that no toolkit can be found, even though RDKit has been installed.

python -m venv ~/venvs/oddt
. ~/venvs/oddt/bin/activate
pip install six
pip install rdkit==2023.3.3
pip install git+https://github.com/oddt/oddt.git@master

Gives this error:

p.s. any chance of a new release on PyPi and CondaForge?
