Comment:
Thank you. What seems to work for me:
```
alias juplab='jupyter lab --app-dir /usr/lib/python3.10/site-packages/jupyterlab'
PYTHONPATH=/usr/lib/sage-9.5.rc3/venv/lib/python3.10/site-packages/ juplab
```
with no further changes to sage.
(The first is some issue with jupyter lab, the second with sage-venv as you say.)

Note that the `./configure --disable-doc` option can be used to suppress the installation of packages needed for docbuilding (see ticket #32759).
