[Ryuji Yokoyama <rqy1319 is4 nyu edu>]

I downloaded RPM format of base programs of Gnome.  Then I tried to  up gradate
using "rpm  -Uvh *" command, but I got following error messages.

failed dependencies:
        gtk+ = 1.0.6 is needed by gtk+-devel-1.0.6-3
        imlib = 1.8.1 is needed by imlib-devel-1.8.1-1
        gtk+ = 1.0.6 is needed by gtk+-devel-1.0.6-3
        imlib = 1.8.1 is needed by imlib-devel-1.8.1-1 

However, I have following files, which I downloaded as parts of base packages.

gtk+-1.2.1-7.i386.rpm
gtk+10-1.0.6-4.1.i386.rpm   
imlib-1.9.5-1.i386.rpm  

Could someone tell me how to solve my problem?  Do I have to do something?  Do
I have to do download other files besides base package in order to use Gnome? 
I am using RH5.2.  

Thanks in advance.
