The same on debian potato:
juergen@theomp12:/tmp$ ldd /usr/bin/gs | grep libc
        libc.so.6 => /lib/libc.so.6 (0x401f2000)
juergen@theomp12:/tmp$ touch libc.so.6 
juergen@theomp12:/tmp$ ldd /usr/bin/gs            
/usr/bin/gs: error in loading shared libraries: libc.so.6: cannot read file data: No such file or directory
juergen@theomp12:/tmp$ cp /lib/libc.so.6 .
juergen@theomp12:/tmp$ ldd /usr/bin/gs | grep libc
        libc.so.6 => libc.so.6 (0x401f2000)
juergen@theomp12:/tmp$
