[Description Joakim Tjernlund 2014-02-12 22:43:34 UTC]

python-updater runs scanelf and stracing scanelf shows:

Do you have a better solution for finding the ELF binaries?

[Comment 2 Maxim Koltsov (RETIRED) 2014-02-13 16:52:45 UTC]

python-updater is pretty obsolete anyway...
It was replaced with better approach with USE-flags dependencies precisely because of this kind of errors.

[Comment 3 Michał Górny 2014-02-13 16:59:22 UTC]

What Maxim said. If you can provide a good patch that fixes this without introducing new issues or stuff like that, we'd be happy to merge it. Otherwise, this is rather WONTFIX since there's no point putting real effort into that mostly-obsolete tool.

[Comment 4 Joakim Tjernlund 2014-02-14 10:06:44 UTC]

Didn't know that it was obsolete an no I don't have a fix either.

Not too long ago I updateted pyton from 3.2 to 3.3 and poterage suggested to run
python-updater and it fixed a few pkgs which suggests that teh new use flag scheme
may need some improvemenets.

Anyhow, you can close the ticket. I am not going to fix something that is
on its way out.

[Comment 5 Maxim Koltsov (RETIRED) 2014-02-14 11:06:45 UTC]

It just means that those packages were not ported to new python eclasses. Such packages are disappearing from the tree right now.
Closing as suggested by mgorny and approved by reporter.
