Caught another trap (renameat). Also, narrowed it down to only being an issue on aarch64, so it's ifdef'ed neatly.

I caught a few of these myself on amd64. Let's wait till your patch lands upstream and then I'll backport or version bump so the fix gets in.
handled upstream in merge request  with patch . Please test and report back upstream to close the issue.
Upstream patch is in for testing (should be in the next release).
Also I'd probably prefer nuking the older ebuilds and stabilizing something reasonably current (1..1.8 looks decent with the patch).
