gnutls-1.4.1-3.el5_4.8 is a moderate security update that required
/usr/libm/libgcrypt.so.11 to have the symbol gcry_cipher_setkey
This is only available in the newer libgcrypt that was released with
SL 5.4.
This update updates libgcrypt in the older SL 5 releases so that
the gnutls security update works correctly.
