Computing dependencies hangs

I am trying to install eclipse on top of a fresh FC4 install. In order to resolve missing packages I was requested to install javamail, xml-commons and java-devel, which I did using yum.
So the next step was to install Eclipse, but it currently hangs checking dependencies. Why? How do I resolve the current situation?

Thanks in advance

You can try stracing it to see where it's hanging.

Thanks lakerdonald, but I had already rebooted my computer and somehow "yum install eclipse" did the trick.
