YUM does not deal with dependencies when remove a package...

Hello,

I have got a problem with dependencies when wan to remove some package
from the system. For instance, when I have installed the httpd, couple
of packages has been installed along with:

# yum install httpd
Loading "tsflags" plugin
Loading "protectbase" plugin
Loading "kernel-module" plugin
Loading "changelog" plugin
Loading "skip-broken" plugin

When I tried to remove the httpd, yum did not deal with the dependencies
and want to remove only the httpd (the dependencies stays installed in
the system):

# yum remove httpd
