Is there not any patch?

Any news?

[Comment 10 Juergen Rose 2018-01-30 16:58:37 UTC]

I suppose I found the reason for the issue. My active python interpreter is Python 3.6.4 but pyelftools was compiled with -python3_6:

root@cheetahnew:/root(27)# python -V
Python 3.6.4
root@cheetahnew:/root(28)# emerge -pv1 pyelftools

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] dev-python/pyelftools-0.24::gentoo  USE="examples" PYTHON_TARGETS="python2_7 python3_4 python3_5 -python3_6" 0 KiB
...



After adding python_targets_python3_6 to =dev-python/pyelftools-0.24 in /etc/portage/package.use the issue disappeared.

So likely we need to use one of the python eclasses to ensure the dependencies stay working.

If someone wants to give https://github.com/gentoo/gentoo/pull/7077 a shot, I believe it will fix this issue.
