[Mono-list] How to find dependencies

[Brian Bilbro]

Background:
A. I'm familiar enough with Linux to be dangerous.
B. I wanted to play around with mono.
C. I have Red-Hat 9.

I downloaded the mono-core for Red-Hat 9 and did (as root):

rpm -i mono-core-1.0.5-1.novell.6.4.i386.rpm

I received the following error:

error: Failed dependencies:
    libicudata.so.26 is needed by mono-core-1.0.5-1.novell.6.4
    libicui18n.so.26 is needed by mono-core-1.0.5-1.novell.6.4
    libicuuc.so.26 is needed by mono-core-1.0.5-1.novell.6.4

I did a google on "libicudata" but that didn't really give me any links to 
understand what I needed to install.  I have two questions:

1. What are those packages above?
2.  Is there a site where I can type in something like "libicudata" and it 
will tell me where to download it?

Thanks,
Brian
