It's just a warning so you can go ahead and use PyChecker. It's hard to call this a bug in PyChecker since it isn't explicitly referring to the regex module; for some reason it is importing all the builtin modules and adding a list of names to the module.

It would be nice if PyChecker trapped the warning and didn't show it. There is already a bug report filed on sourceforge - http://sourceforge.net/tracker/index.php?func=detail&aid=1236534&group_id=24686&atid=382217 - so I would ignore it and move on.
