[CentOS] Jabberd and Centos 3.4

I am trying to setup a local Jabberd server for our members of our IT department to use. I downloaded the source for 2.0s8 from the jabbered site. When i run ./configure I receive the following error:

"configure: error: Libidn >= 0.3.0 not found"

I went out to dag and downloaded and installed the libidn-0.4.6-1.1.el3.dag rpm. When i ran ./configure again it failed again. After a little searching on Google I found the following article:

http://mail.jabber.org/pipermail/jadmin/2004-June/016435.html

Following its advice I rand ./configure --with-extra-library-path=/usr/lib/libidn.so.11. However it still fails. Anyone have any ideas? I don't know anything about libidn, is 0.4.6 incompatible with versions needing 0.3.0?

Thanks,
