hm.. Sometime, PyDev say \"Unresolved import error\". In my environment
Python2.6.6 Eclipse3.7 PyDev2.2.2
Errors are.
I was having a similar problem with the dbfpy module.
I had downloaded the tar archive and installed the source files in /usr/lib/python2.7/dist-packages
With this I was able to import the packages in IDLE and even run the code in Eclipse. However the pydev import was still showing as an error with the message "unresolved import"
As suggested by Fabio, I checked the PyDev documentation for forced-builtins. Just adding the name of the package ("dbfpy" in my case to the Forced Builtit tab of Python Interpretr in Eclipse) solved the issue.
