Forum OpenACS Q&A: Response to libpq.so.2 is not working for 80 port

[postgres@localhost lib]$ ldd libpq.so.2
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x40015000)
        libresolv.so.2 => /lib/libresolv.so.2 (0x40043000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x40056000)
        libc.so.6 => /lib/i686/libc.so.6 (0x4006d000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaaa000)

 then I did: 

[postgres@localhost lib]$ su -
Password: 
[root@localhost /root]# chown 777 /lib/libcrypt-2.2.2.so
[root@localhost /root]# chown 777 /lib/libresolv-2.2.2.so
[root@localhost /root]# chown 777 /lib/libnsl-2.2.2.so
[root@localhost /root]# chown 777 /lib/i686/libc-2.2.2.so
[root@localhost /root]# chown 777 /lib/ld-2.2.2.so


But it didn't work anyway....
