Possibly an RPM artifact -- see: Bug 3252

 Subject: ldconfig-errors
 
ldconfig: /usr/lib/libstdc++.so.2.9 is not a symbolic link
 
ldconfig: /usr/lib/libstdc++-libc6.1-1.so.2 is not a symbolic link

(ldconfig should run silently)

The two listed files _should_ be links, rather than direct files:

[root@localhost src]# cat /etc/ld.so.conf 
/usr/X11R6/lib
/usr/kerberos/lib
/usr/i486-linux-libc5/lib
/usr/lib
[root@localhost src]# ls -al  /usr/lib/libstdc++.so.2.9
-rwxr-xr-x    1 root     root         5380 May 26 12:29
/usr/lib/libstdc++.so.2.9
[root@localhost src]# ls -al /usr/lib/libstdc++-libc6.1-1.so.2
-rwxr-xr-x    1 root     root      1185378 May 26 12:29
/usr/lib/libstdc++-libc6.1-1.so.2
[root@localhost src]# 

Reproduce the error thus:

 src]# ldconfig -v > /dev/null
ldconfig: Path `/usr/lib' given more than once
ldconfig: /usr/lib/libstdc++.so.2.9 is not a symbolic link

ldconfig: /usr/lib/libstdc++-libc6.1-1.so.2 is not a symbolic link

[root@localhost src]#
