anyone with a Mac, HEEELP

Can a friendly mac user please try and un-stuffit this file for me:

http://quake.chaoticbox.com/downloads/equakeutils.sit

and ideally ZIP it for me?

Please... I'm on Linux and can't unpack this SIT archive however much I try, and all the obscure software I downloaded failed to do much.

I really need the contents, though. It's a Quake qbsp compiler and similar stuff.

Edit: [SOLVED]

I was finally able to un-stuffit this archive using this tool:

http://wakaba.c3.cx/s/apps/unarchiver

Very obscure tool, but it does extract stuffit archives under Linux.

All other options I tried, such as Ubuntu's macutils and programs such as unsit, unstuff etc. did NOT work. This one finally did.
