[CentOS] Can't install 3 needed packages.

[Sebassje]

Hello,

Ik have searched trough 15 pages on this form, but couldn't find the answer..
The problem is, i do exactly what the install doc say's..
Everything works, but the 3 links:
wget http://www.thatfleminggent.com/packages/...f.i386.rpm
wget http://www.thatfleminggent.com/packages/...f.i386.rpm
wget http://www.thatfleminggent.com/packages/...f.i386.rpm

So, i heve searched om http://www.thatflemminggent.com and found the packages version 0.62..
But after this code i get errors: rpm -i courier-authlib-0.60.6-1.el5.mf.i386.rpm

Warning, courier-authlib-0.60.6-1.el5.mf.i386.rpm conflict in courier-authlib-0.60.6-1.el5.mf.i386.rpm something like that..

I am now more then ten hours busy with this..

Who can help me with this?
Thank you very much!

Sebas.
