Steam and 64 bit Ubuntu 10.10

So, looking here http://www.arsgeek.com/2008/08/18/how-to-run-a-dedicated-steam-server-on-your-ubuntu-box-countestrike-style/ on how to run a dedicated steam server - but I kept getting this error:

./hldsupdatetool.bin
unable to execute ./hldsupdatetool.bin: No such file or directory.

Thankfully this guy: http://mag.entropy.be/blog/ figured it out - it was a dependency - libc6-i386 wasn't installed - so go team!
