[Icecast] Problem installing. Please help

[Sam]

Hello. I am trying to install icecast on redhat 9.0 with cpanel
I have the latest stable release of everything installed on my server.

Problem 1: 
When I try to install icecase via rpm, I get this error:
error: Failed dependencies:
        curl >= 7.10.0 is needed by icecast-2.2.0-1
        libtheora is needed by icecast-2.2.0-1
        libtheora.so.0 is needed by icecast-2.2.0-1

Note: curl version I have installed:
curl 7.12.0 (i686-pc-linux-gnu) libcurl/7.12.0 OpenSSL/0.9.7a 
zlib/1.1.4


Problem 2:
I downloaded libtheora-1.0alpha4.tar.gz and tried to configure and 
install. I get:
checking for ogg >= 1.1... Package ogg was not found in the pkg-config 
search path.
Perhaps you should add the directory containing `ogg.pc'
to the PKG_CONFIG_PATH environment variable
No package 'ogg' found
checking for Ogg... yes
checking for oggpackB_read... no
configure: error: newer libogg version (>1.0) required
root at www [/usr/src/libtheora-1.0alpha4]# libogg -v
-bash: libogg: command not found


Can someone please tell me what I need to do to get rid of these 
problems?
Thanks so much.
