[Cooker] Why urpmi does not install dependent RPMs?

[Borsenkow Andrej]

[root@cooker cooker]# rpm -q --requires -p
/mnt/hd/i586/Mandrake/RPMS/Bastille-T
k-module-1.2.1-0.1mdk.noarch.rpm 
perl-Tk  
Bastille  
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(CompressedFileNames) <= 3.0.4-1
[root@cooker cooker]# urpmi Bastille-Tk-module
installing
/mnt/hd/i586/Mandrake/RPMS/Bastille-Tk-module-1.2.1-0.1mdk.noarch.rpm
error: failed dependencies:
        perl-Tk is needed by Bastille-Tk-module-1.2.1-0.1mdk

So, perl-Tk is explicitly listed as needed by Bastille-Tk and is
correctly listed in depslist.ordered. Why is it not installed?

[root@cooker cooker]# rpm -q urpmi
urpmi-1.7-4mdk
