Yum-like package list?

[G. A. Gallup]

Yes, this works if you know 'blah'.  However, my initial install  
(x86-64) would not run dynamically linked 32-bit apps.  Is there any  
way to know the package name to install is 'ia32-libs'?  Google  
finally told, but I couldn't figure out how to make the KUNBUNTU  
system tell me this.
