chillenb [1] filed an orphan request for python-pyscf [2]: PySCF is at version 2.6.2 already. Would you mind updating the PKGBUILD? I am going to be using it full time for the next four or so years (and submit pull requests occasionally) so I would be happy to maintain the PKGBUILD if you no longer wish to do it.
