On a rolling distro, do not install packages outside the package manager. Eventually you will loose track of what files were installed where and when file conflicts then occur you have no idea where they are coming from.
Also with something like this, upstream might just ship something for Debian based only, so you will need to adjust for this distribution.
Thus, make sure to read and use the Packaging Guide, there will be usable PKGBUILDs as a starting point. Probably start looking in AUR (linked and explained for you in the Guide).
