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

New package: nebula-1.0.0
https://github.com/void-linux/void-packages/pull/17005

Description:
Currently only supports x86_64, arm, and aarch64 targets (glibc and musl).

I'm working on patches for upstream to add i686 support, but that's not for this version. Would likely need to do the same for PowerPC support.
