How to check for dependencies on a specific program?

Hello everybody.

I'm trying to run Steam on Fedora 17 x64.

The program installs, but it won't run. I think the cause of this it's because the program is trying to find some files that refer to the 32 bit libraries, which I already have installed, but it still doesn't work.

So I'm wondering, how can I check for the dependencies for this program?
My idea is that once I know what components are missing, I can install the packages manually.

Thanks.
