Curious problem with yum

[Timothy Murphy]

I recently ran "yum update" and encountered a conflict
with iptstate requiring libnetfilter.conntrack .

OK, that is simple enough;
but if I remove iptstate
I can then re-install it without any problem.
---------------------------------------
[tim at rose ~]$ sudo yum remove iptstate
...
  iptstate.i586 0:2.2.1-5.fc11

Complete!
[tim at rose ~]$ sudo yum install iptstate
...
Installed:
  iptstate.i586 0:2.2.1-5.fc11

Complete!
---------------------------------------
Why don't I get the dependency problem here?
I still get it if I run "yum update" again.
---------------------------------------
[tim at rose ~]$ sudo yum update
