Comment (by Chris Johns):

 I cannot repeat the error. I have installed `Python 3.8.5` on FreeBSD 12
 and successfully run:
 {{{
 python3.8 -m venv sphinx38
 . ./sphinx38/bin/activate
 pip install --upgrade pip
 pip install Sphinx
 pip install sphinxcontrib-bibtex
 cd rtems-docs.git
 ./waf distclean configure
 }}}
 The `pip` configuration is:
 {{{
 (sphinx38) ruru rtems-docs.git $ pip list
