python can't retrieve feed from https in planetplanet

so I recently tried to install planetplanet as a website to aggregate interesting blogpost. and it works fine for blog that uses http, but when it come to https, the feeds doesn't work. and I want to know are there any workaround to enable python to retrieve feeds from sites that uses HTTPS? since planetplanet uses python script to functions so I guess there must be some code that need to be added to make it recognize https feeds and retrieve it. any help would be appreciated. thanks.
