Textblob 0.9 broke compatibility

[matheuscas]

After upgrade to latest version of Texblob (0.9.0 - 2014-09-15), text blob-aptagger has broken. The following error raised:

----> 1 from textblob_aptagger import PerceptronTagger

/Users/matheuscas/Envs/pesquisa/lib/python2.7/site-packages/textblob_aptagger/__init__.py in <module>()
      6 '''
      7 from __future__ import absolute_import

     11 from textblob.exceptions import MissingCorpusException
     12 from textblob_aptagger._perceptron import AveragedPerceptron

ImportError: No module named packages

Besides that, I think I found some other problems like

Backwards-incompatible: MissingCorpusException to MissingCorpusError.
