Actually I think the issue is always there(at least from when python was upgrade to 2.7.x).
e.g., in target, run "python" and try "import grp", we'll get an error saying the built-in module grp couldn't be found; in python's log.do_compile, we can see the obvious warnings.

I'm trying the task "self hosted image"(https://wiki.yoctoproject.org/wiki/Build_Appliance_Design):
in target, I found bitbake's do_package failed because "import grp" failed, so I had to look into the issue.
