Mudlet 3.0.0-delta not working on Antergos

[Mami]

It just doesn't run when I click it. if I do this:

Code: [show] | [select all] lua

[mami@AntergosDudels ~]$ /home/mami/mudlet-3.0.0-delta/bin/run-mudlet.sh
./mudlet: error while loading shared libraries: libicui18n.so.52: cannot open shared object file: No such file or directory

Still does not run. I try this:

Compiling in ArchLinux

The best way to do this would be to use the PKGBUILD found here. You'll just download the PKGBUILD into a directory, run
makepkg
sudo pacman -U [name of the generated pkg file]
and you'll be done. For more info on what this does, visit this site

and the link for the pkgbuild says 404 page not found. Help pls?
