Since 2.0, this package use the system lrmi library which is not available in EL. I have to temporary bundled it to be able to update to 2.5 (this is a very small file, only used on i386).

This tool is required by ocsinventory-agent.

Thanks goes to fr.CentOS.org users which test this new package.
