Had this issue when you’ve been trying to run something like Funnelweb, and you hit an ImportError for BeautifulSoup? You’re definitely not alone, because I just hit the same issue. The answer is simple — just ensure that you don’t use BeautifulSoup 4 or above (this is still beta) — it uses a different namespace, specifically bs4. Thus, whilst you might have the BeautifulSoup egg satisfying your dependencies, any imports of this package are going to fail.
For me, I’m using buildout, so I just pinned my version of BeautifulSoup thusly:
[buildout] ... versions = versions [versions] BeautifulSoup = 3.2.0
Now, we stop using BeautifulSoup 4.0 and everything works again.

Leftovers are typically useful when they’re in your fridge at home. They mean you don’t have to mess around making lunch for the next day for work, and can just grab them, and walk right out the door. Now, leftovers in the zope.component SiteManager aren’t so nice, especially when some Plone products fail to remove what they’ve registered. The consequences of this are that you’ve got references left which will break things when you uninstall/remove the physical eggs/files. These leftovers would be ones would be mutated food that comes to kill you after you’ve thrown it in the bin, assuming we follow the same analogy. But how to fix them?

Here’s an interesting error message I got stumped with for a good set of hours. The issue started with me using collective.autoreload with Plone and it does the trick, mostly. With any such ‘operation’ and live reloading of code for Python, you’ve got to expect that not everything will go according to plan. Most things do, but one issue I found presented with this error message:
