During an "emerge -avuDNt world", my installation of pylint (0.8.1) which was already installed, asked to install the new package astng. Unforuntately this fails with FEATURES="collision-protect" enabled, as follows: >>> Completed installing astng-0.13.1 into /var/tmp/portage/astng-0.13.1/image/ * checking 35 files for package collisions existing file /usr/lib/python2.4/site-packages/logilab/__init__.py is not owned by this package * spent 0.0382580757141 seconds checking for file collisions * This package is blocked because it wants to overwrite * files belonging to other packages (see messages above). * If you have no clue what this is all about report it * as a bug for this package on http://bugs.gentoo.org package dev-python/astng-0.13.1 NOT merged No package files given... Grabbing a set. Reproducible: Always Steps to Reproduce: 1. Have a previously emerged copy of pylint and logilab (perhaps with --nodeps to recreate) 2. Attempt to emerge astng. 3. Actual Results: The emerge failed with the error message above Expected Results: The installation fails, most likely not writing to the logilab directory, but just to the underlying astng directory. I'm not sure whether this is altering the logilab files to register it as a plugin, or whether it's just trying to install on top of it.

I just fixed astng-0.14.0 to not install this file and depend on logilab-common (sorry for missing this when I versionbumped astng: I do have collision-protect in FEATURES but I had installed astng 0.13.1 with collision-protect disabled, which caused it to not warn about 0.14.0). I also revbumped logilab-common to make sure it installs an __init__.py (otherwise people without collision-protect unmerging the previous version of astng will break logilab-common). Closing, reopen if I missed anything.
