When i try to start steam i get the following output/error

JuHwon ~ $ steam
/home/hown/.local/share/Steam/steam.sh: line 161: VERSION_ID: unbound variable
/home/hown/.local/share/Steam/steam.sh: line 161: VERSION_ID: unbound variable
Running Steam on arch  64-bit
/home/hown/.local/share/Steam/steam.sh: line 161: VERSION_ID: unbound variable
STEAM_RUNTIME is enabled automatically
Error: You are missing the following 32-bit libraries, and Steam may not run:
libc.so.6

This occurs since i last updated the steamclient yesterday.
Though when i check the libc.so.6, everthing seems fine to me.

JuHwon ~ $ pacman -Qo /usr/lib/libc.so.6
/usr/lib/libc.so.6 is owned by glibc 2.21-4

JuHwon ~ $ pacman -Ss glibc
core/glibc 2.21-4 (base) [installed]
    GNU C Library
extra/nss-mdns 0.10-6
    glibc plugin providing host name resolution via mDNS

JuHwon ~ $ ls -l /usr/lib32/libc.so.6
