permission problems

[Amadeus W.M.]

On a newly F11 i386 installation:


[root at phoenix ~]# /sbin/iptables -L --line-numbers
/sbin/iptables: error while loading shared libraries: libiptc.so.0: 
cannot open shared object file: Permission denied

[root at phoenix ~]# ls -l /usr/lib/libiptc.so.0*
lrwxrwxrwx. 1 root root    16 2009-07-13 00:28 /usr/lib/libiptc.so.0 -> 
libiptc.so.0.0.0
-rwxr-xr-x. 1 root root 43196 2009-03-30 09:04 /usr/lib/libiptc.so.0.0.0


So permissions seem ok.



Or, for instance, 

[root at phoenix ~]# /etc/rc.d/init.d/autofs start
Starting automount: automount: error while loading shared libraries: 
libgssglue.so.1: cannot open shared object file: Permission denied
                                                           [FAILED]
[root at phoenix ~]# ls -l /usr/lib/libgssglue.so.1*
lrwxrwxrwx. 1 root root    19 2009-07-13 00:28 /usr/lib/libgssglue.so.1 -
> libgssglue.so.1.0.0
-rwxr-xr-x. 1 root root 31516 2009-02-25 10:35 /usr/lib/
libgssglue.so.1.0.0
[root at phoenix ~]# ls -l /usr/lib/libgssglue.so.1*
lrwxrwxrwx. 1 root root    19 2009-07-13 00:28 /usr/lib/libgssglue.so.1 -
> libgssglue.so.1.0.0
-rwxr-xr-x. 1 root root 31516 2009-02-25 10:35 /usr/lib/
libgssglue.so.1.0.0


Directory permissions also look fine:


[root at phoenix ~]# ls -ld /usr
drwxr-xr-x. 14 root root 4096 2009-07-13 00:30 /usr
[root at phoenix ~]# ls -ld /usr/lib
drwxr-xr-x. 141 root root 69632 2009-07-14 20:08 /usr/lib


Does anyone have any idea what should I look into? SELinux maybe?
