Reverse conflicts early remove for package

Hi:

I'm building a repo, but obviously I got something wrong.  When I run 
apt-get I get:

[root@brain root]# apt-get install python-tkinter
Reading Package Lists... Done
Building Dependency Tree... Done
The following NEW packages will be installed:

However, if I just install with rpm, it's okay:

[root@brain archives]# pwd
/var/cache/apt/archives
[root@brain archives]# rpm -ivh 
python-tkinter_2.3.4-3.0.rh9.pyv_i386.rpm

Currently, I have another tkinter packaged named "tkinter" at version 
2.2.2.

Let me know where I can look.

thanks,
