[Python-projects] libastng installation problem

[Tom Crawley]

Hi,
 
 I am attempting to install pylint v0.14.0.
 
 I am using the following components:
 
 pylint version 0.14.0
 logilab-astng v 0.17.2
 logilab-common v 0.34.0
 
 It seems that astng is not installed correctly as it cannot be loaded or imported.
 
 Here is traceback

 I have tried both easy_install and setup.py install from the command line using the uncompressed packages.
 
 I also tried this is a virtualenv sandbox which also failed with the error shown above.

 I get the errors below when trying to install pylint.

 What am I doing wrong ? Is there any information which you need to diagnose the problem.
