Comment 2 for bug 320253

Dear Nikola,

Thanks a lot for your patience and testing.

To permanently fix this and provide users with a better feedback it would be beneficial to check these prerequisites before executing the playground.py docu command. I don't think we should add these packages to the official dependency list, because most of the people will only download the latest official documentation from the website and will not build it on their own.

Does anybody have an idea how to implement a check in the docu command to test if the prerequisites above are met?

Best Regards,
  Daniel
