Error Encryption Support Not Enabled

when I run the following GET commad:
./snmpget -m ALL -M /data/net/naamab/snmp/snmp_mib/ -v 3 -a MD5 -l authPriv -u test1 -A welcome1 -x DES -X privpass 127.0.0.1 NOVELSAT-MODULATOR-MIB::nsModLineCMMode.0 -d

I get the error:

Encryption support not enabled.

snmpget: USM encryption error

I have defined a user (and user, view and access) that should work with encryption:
snmpd.conf:
createUser test1 MD5 welcome1 DES privpass
group debugGroup usm test1
view debugView included .1
access debugGroup “” usm priv exact debugView debugView none

general details:
I am using net-snmp on linux embedded
version 5.5
Configuration (part of it):
./configure –target=mips64-octeon-linux-gnu
–build=mips64-octeon-linux-gnu
–host=i686-pc-linux-gnu
