Arch Linux - make: error while loading shared libraries: libunistring

I keep getting this same error when trying to install various packages: make: error while loading shared libraries: libunistring.so.0: cannot open shared object file: No such file or directory It's occurred while trying to install the Ruby gem Gosu as well as some free Linux games like Alien Arena. I even tried re-installing libunistring with pacman to no avail.
