make install problem: CRITICAL

[Bhupendra Wakankar <bhupen at engr dot uconn dot edu>]

Hi.
I am trying to install glibc2 as my primary C library and using the
following files and add-ons
glibc-2.0.6.tar.gz
glibc-linuxthreads-2.0.6.tar.gz
glibc-crypt-2.0.6.tar.gz
glibc-localedata-2.0.6.tar.gz

The compilation proceeded smoothly. before installing, I backed up my
old header files into a separate directory  (as per directions given in
http://www.redhat.com/mirrors/LDP/HOWTO/Glibc2-HOWTO-5.html ) and moved
the old C libraries as well.

after that when I typed make install
I got the following error message
------------------------------------------------------------------

------------------------------------------------------------------

now I cannot use any commands mv, cp, ln, ls or any other.
I get the message

ls: /lib/libc.so.6: no version information available (required by ls)
ls: error in loading shared libraries: /lib/libc.so.6: undefined symbol:

What is the problem here and how can I fix it?
Any suggestions would be a great help...

Thanks
