Hi,hello
The package has no maintainer currently, feel free to adopt it yourself by clicking the "Adopt Package" button in the "Package Actions" menu (you have to be connected to your AUR account to do so).
i'm the project maintainer of Google Benchmark which is in AUR as benchmark-git (https://aur.archlinux.org/packages/benchmark-git). the AUR package is out of date, and i've confirmed with the current maintainer (cc'd) that they're happy for me to take over and update it.
my username on AUR is dma.
thanks
