libmcryp rpm install issue

Hi all:

I am try to install libmcryp rpm pack but it came with those message:

[root@localhost ~]# rpm -Uvh /tmp/libmcrypt-2.5.8-9.1.el6.i686.rpm
warning: /tmp/libmcrypt-2.5.8-9.1.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID f21541eb: NOKEY
error: Failed dependencies:
        libc.so.6 is needed by libmcrypt-2.5.8-9.1.el6.i686
        libc.so.6(GLIBC_2.0) is needed by libmcrypt-2.5.8-9.1.el6.i686
        libc.so.6(GLIBC_2.1.3) is needed by libmcrypt-2.5.8-9.1.el6.i686

        libc.so.6(GLIBC_2.4) is needed by libmcrypt-2.5.8-9.1.el6.i686

Then I install the glibc-2.12-1.7.el6.x86_64 from the CD. then install the libmcrypt again it come same error messages. so what did I miss?
