Evolution on RedHat 7.2

[Matt Alexander]

I tried the "lynx -source http://go-gnome.com/ | sh" method, but got this
error after clicking the Next button to install:

ERROR: Unable to download channel information.

Any comments or suggestions from the audience?
I'm running RH 7.1, and I didn't click the Gnome button during the initial
install of RH (I only wanted KDE at the time), so it's possible I'm
missing some critical packages (although it would seem that go-gnome.com
would be able to install them for me).
