I build calibre from source from
http://status.calibre-ebook.com/dist/src. Everything worked fine, however it is now prompting me for an upgrade to 0.8.6. I'm pretty sure it is 0.8.6 as it has the new get plugin thing, but calibre --version tells me I have 0.8.5 as well so I guess the correct version wasn't put in the update.
