Need help. Developers wants a older versions of gcc to be installed on redhat.

[unix syzadmin]

Hi,

We have a RHEL AS4 U3 server. It has gcc-3.4.5-2 installed.
Developers want a older versions of gcc to be installed  (*gcc-3.2.3-20)*.

How can I uninstall gcc-3.4.5-2 and all its dependants.
Also, is there a way to download *gcc-3.2.3-20 *and all rpm's that it needs
simultaneously.  I have access to rhn.redhat.com .
Please suggest.
