LinuxQuestions.org - SNMP error when running MRTG: no response

anybody helps?

I installed MRTG under /usr/local/mrtg-2 and installed SNMP under /usr/local/net-snmp

then I did the foloowing step:
cd /usr/local/mrtg-2/bin
cfgmaker --global 'WorkDir: /home/httpd/mrtg' \
--global 'Options[_]: bits,growright' \
--output=/home/mrtg/cfg/mrtg.cfg \
public@my_linux_IP_address

and I got the error message like this: from the error message, it seems that SNMP is not installed properly. this is what I did to install SNMP,
I downloaded the net-snmp-*.tar.gz under /usr/local/src
unpack it,
cd /usr/local/net-snmp-5.0.9
./configure --prefix=/usr/local/net-snmp
make
make install
:(
