There's a merged pull request on the void-packages repository vdirsyncer: cherry pick Python 3.9 fixes. https://github.com/void-linux/void-packages/pull/25598 Description: vdirsyncer uses the deprecared iter() method. Python 3.9 removed this method. Upstream has a fix (commit 7577fa21177442aacc2d86640ef28cebf1c4aaef), but has not spun a new release. This commit cherry-picks that commit and bumps the revision.
