No AUR, no PKG.
To make, or to makepkg?
It does however have a Makefile, and a config shell-script. But after reading through them, I'm not convinced this is compatible with the Arch philosophy.
Is it recommended that I make a PKGBUILD, or is there another way to install it correctly? What is best practice?
I know that how to get it to work, more or less. I want to do this the Arch Way. Not to simply hack it together. I want to really learn how Linux works.
