To obviate this problem, I devised a solution with the repackage package, which has worked for me for some time. It adds the upper directory to the lib path:

repackage.up()
from mypackage.mymodule import myfunction

Repackage can make relative imports that work in a wide range of cases, using an intelligent strategy (inspecting the call stack).
