<sigh> I have managed to hack around the issue with the following command ...

 pip install sphinxcontrib-bibtex==0.4.1

I am waiting for the build to be posted in the web server.



The sync.rtems.org box is running FreeBSD 10 and Amar and I cannot update this
box with a lot of unfunded work and we both do not have this time available. In
time things will stop working. We need financial support from the community and
users to be able to fund such work. I have been attempting to get a donate page
online but I am sorry this still has not happened so if you would like to donate
please send me Joel a private email with the details and we will attempt to get
something happening. Thanks.
