[CentOS] minimal installation - kickstart error

Hi

I have inherited some kickstarts that attempt to remove some packages 
that at some point its been deemed they are not required.
I am migrating all this over to cobbler but trying to get to the bottom 
of this error that although the kickstart completes sshd cant start as 
the package nss is not installed.

It fails with this

Installing nss - 3.11.99.5-2.el5.centos.x86_64
error: %pre(nss-3.11.99.5-2.el5.centos.x86_64) scriptlet failed, exit 
status 255
error:   install: %pre scriptlet failed (2), skipping 
nss-3.11.99.5-2.el5.centos

Which seems to happen due to this

error while loading shared libraries: libssl3.so

yum tells me

# yum provides libssl3.so
nss.i386 : Network Security Services
nss.i386 : Network Security Services

so

# yum search "Network Security Services"
nss.i386 : Network Security Services
nss-tools.x86_64 : Tools for the Network Security Services
nss-devel.x86_64 : Development libraries for Network Security Services
nss.x86_64 : Network Security Services
nss-devel.i386 : Development libraries for Network Security Services
nss-tools.x86_64 : Tools for the Network Security Services
mod_nss.x86_64 : SSL/TLS module for the Apache HTTP server
nss.i386 : Network Security Services

But anyone know what package messing this up as from what i can see 
nothing there is being 'removed' in the kickstart - below is a full list 
of packages removed in the kickstart

thanks for any tips
