cyrus sasl 2.1.26 des.h: No such file or di rectory

Hello experts,
I'm trying to install cyrus_sasl VERSION "2.1.26" from source:
./configure --enable-auth-sasldb --with-dbpath=/var/lib/sasl/sasldb2 --with-saslauthd=/var/run/saslauthd --with-ldap;make;make install
and have following message:
auth_getpwent.c:57:20:fatal error: des.h: No such file or directory
When I search for des.h:
[root@localhost cyrus-sasl]# find / -name des.h
/usr/local/ssl/include/openssl/des.h
/usr/src/kernels/2.6.32-358.el6.x86_64/include/crypto/des.h
