Hi A novice user who just discovered this wonderful utility, encountered the following error while trying the -r option. Here is the complete error info:

Please let me know is the issue related to Beautifulsoup? I am able to infer, some parser for lxml is missing, but not sure which one.

I had the same issue and I suppose it is only present in the homebrew build as I tried with APT on Ubuntu and it works fine. To fix the issue I installed lxml via brew - brew install python-lxml.
