ImportError (No module named pystruct.inference)

This error happens when you run nosetest . command. The funny thing is that my system has pystruct package installed via pip. I tried pystruct 0.2.4 and 0.3.2 as well but no luck.

ERROR: Failure: ImportError (No module named pystruct.inference)

Because of this, I guess the cor.COR() does not work either since the import statement is failing in that class as well.
