[Python-projects] ImportError importing astng.utils instead of logilab.astng.utils

[Gunnlaugur Thor Briem]

Hi again,
I got past this by chucking the egg installation and building from source.

Are the eggs known to be an unreliable installation method for pylint/astng?
If so, I suggest a well-placed warning to that effect on the pylint (or
astng) webpages.

Regards,
