ekey driver compatibility issues during installation on Centos 5.6

[Maciej Domanski]

Hello All,

I was trying to install entropy key on Centos 5.6 64 bit 
2.6.18-238.12.1.el5xen, following instructions for Centos 5.5 available 
on simtect's website: ekey compatibility issues during installation on 
Centos 5.6. I searched mailing list archive but there was nothing 
referring to the problem I have.

Below is set of errors returned when trying to install ekeyd:

root at foo:10:51:03entropy_key# rpm -i ekeyd-1.1.4-1.x86_64.rpm 
ekeyd-ulusbd-1.1.4-1.x86_64.rpm lua-5.1.4-2.x86_64.rpm 
lua-socket-2.0.2-4.x86_64.rpm
         package lua-5.1.4-2.el5.rf.x86_64 (which is newer than 
lua-5.1.4-2.x86_64) is already installed
         file /usr/bin/lua from install of lua-5.1.4-2.x86_64 conflicts

         file /usr/bin/luac from install of lua-5.1.4-2.x86_64 conflicts

root at foo:10:54:15entropy_key# rpm -e lua-5.1.4-2.el5.rf.x86_64
error: Failed dependencies:
         lua is needed by (installed) rrdtool-1.4.4-1.el5.rf.x86_64
root at foo:10:54:39entropy_key# rpm -i ekeyd-1.1.4-1.x86_64.rpm 
ekeyd-ulusbd-1.1.4-1.x86_64.rpm
error: Failed dependencies:
         liblua-5.1.so()(64bit) is needed by ekeyd-1.1.4-1.x86_64
         lua-socket is needed by ekeyd-1.1.4-1.x86_64

That means that lua used by rrdtool is newer than supplied by simtec. I 
do not want to remove rrdtool nor roll it back to older version as that 
would mean destroying my configuration for several reporting programs. I 
don't see any reasons to upgrade entire system. I would like to avoid 
"-force" option too.
There is a warning on simtec's website :"System crashes, which may 
require a physical system reset. This is especially problematic and 
common on RHEL 5/CentOS 5. Always use the userspace driver."
What can I do in these circumstances to install the product without 
harming system or installed programs? Has anyone had problem like this?

Best Regards
Maciej
