Likely because it needs libssl-dev, which I already had installed. (That's the apt package name, not sure what the arch equivalent is.) It dependsd on libgit, hence the libssl

... or maybe it's built with different flags? because the aur does list libssl https://aur.archlinux.org/packages/gitopolis
🤷 had a google but really not sure
