Kovid (or whomever cares),

Because I get a sort-of nag on calibre to upgrade to a newer version (I am running v.0.4.56) I thought I'd hit it with easy_install (on Gentoo). I spent a lot of time in dependencies hell (I try to limit the number of unmasked packages) when I finally narrowed down the problem to a library that I don't think I even have installed: PictureFlow. I don't want to install something that I can't uninstall (I hate how easy_install bypasses package management), so I backed out the upgrade to version 0.4.56. What am I missing?
