There's a closed pull request on the void-packages repository

New package: neochat-1.0
https://github.com/void-linux/void-packages/pull/27385

Description:
libQuotient was renamed from libqmatrixclient. The current version of Quaternion looks for libqmatrixclient. Once new version of Quaternion is released we can remove libqmatrixclient. So add conflict with libqmatrixclient until then
