How do you go about discovering what rpm to install to add a required library when trying to compile an application? Current example: I want to try out Tomboy ( http://beatniksoftware.com/tomboy ). ./configure gives me the following error: No package 'gdk-2.0' found I've tried doing a 'yum search' and have tried rather randomly installing a couple of rpm's with the string 'gdk' in them, but that seems a pretty dumb approach. Is there a better one, or do you just have to read and comprehend the code to know what to install?
