Installing Calibre in Arch Linux

[jatz]

Edit: Disregard that, problem solved, using outdated tool

Hey all, I'm trying to install calibre on arch linux. I seem to have some kind of permissions in compiling it, if anyone could help that'd be great.

Below is the terminal output I get when trying to compile/install it. I've bolded the error itself and what I think may be related.
