I rebooted the server, and it works. But yum does not work anymore,
apparently due to some conflict between rpmlibs and selinux.

2.3.4 (#1, Feb 22 2005, 04:09:37)
[GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)]


These are the relevant rpms that I have installed in my system:

any suggestion?

Thanks in advance,
