Net-SNMP-5.3 - error in make - when using --disable-mib-loading: undefined reference to `get_tree'

Hey,
 
while building net-snmp-5.3, and trying to reduce memory size...
 
I get an error in 'make', only when I add the token
--disable-mib-loading, in the ./configure line:
 
[my configure line looks like this, when I add the token]
---------------------------------------------
./configure --with-mib-modules="agentx" \
            --prefix="/usr/local/net-snmp-5.3" \
            --program-suffix="_5.3" \ \
            --with-persistent-directory="/var/net-snmp-5.3"\
            --with-sys-location="def-location"\
            --with-sys-contact="no-contact"\
            --with-default-snmp-version="1"\
            --with-logfile="/var/log/snmpd-5.3.log" \ 
            --disable-debugging \
\
            --disable-mib-loading \

 
 
the error I get when I commit 'make' is:

Any ideas?
