hm.. Sometime, PyDev say \"Unresolved import error\". In my environment
Python2.6.6 Eclipse3.7 PyDev2.2.2
Errors are.
Adding the corresponding package folder ending with '.egg-info' to PyDev > Interpreter - Python - library will resolve the problem.
In Linux, it is usually under /usr/local/lib/pythonX.X/dist-packages
