I've noticed that some systems don't have redhat-lsb or even redhat-lsb-core installed and as a side effect, the ocsinventory agent reports them as 'linux' instead of Centos with the release version. Also, where it is installed and ocsinventory does pick up the name, it doesn't include Centos (pre-7.x) in the 'all Linux' grouping because the name is just CentOS and unlike 'Red Hat Enterprise Linux, or 'SUSE Linux Enterprise Server' which include Linux in the name.
Anyway, a few questions:
Is there some reason to omit redhat-lsb-core from any of the install groups?
Why is there such a big list of dependencies? (glibc-devel, gdbm-devel, perl-CGI, etc., seem odd as 'standard requirements').
Even more so for the full redhat-lsb package? Why are things like qt and ghostscript pulled in by dependencies?
