Well, while it is on the mirror - Yum will not download/install it. I 
was able to download fine via wget and install via rpm.  I believe the 
yum error "Package does not match intended download" is likely a better 
indicator of the problem and the following "Requested Range Not 
Satisfiable" errors are a byproduct - perhaps an error in yum or a 
library it uses.

I just found a thread entitled "Update fails with "Package does not 
match intended download"" on the Centos PHPbb forums and it has a fix 
(have not tried myself). The fix is to disable the fastestmirror plugin 
by editing the /etc/yum/pluginconf.d/fastestmirror.conf
http://www.centos.org/modules/newbb/viewtopic.php?topic_id=19479&forum=37

I also found reference to the same error and problem during the CentOS5 
-> 5.1 release. I'm not sure what the fastest mirror plugin is doing 
(perhaps caching old data?), but it does not seem that it is being 
tested thoroughly by Q/A during these respins.

Perhaps this clue will help others...
