Strangely enough, I can run portal 2 from command line without having steam running... Doesn't help the crash, but it's just strange AFAIK all games acquired through steam require steam running...
How exactly do you run it (provide the full command, please)? Did you apply any "patches"? Did you checked the game files integrity before run? Did you install it on windows or using wine only? Any winetricks or pure prefix?
