How to add MIB in pre installed snmp package

[deepak.sachan deepak.s. <dee...@de...>]

 Hello friends
I have got a new hardware in which linux3.0 is runninig with snmp packg installed.
How we can add a new MIB in pre installed snmp package in kernel or  installed with sudo apt-get install snmpd ?. As there is no source code( so where to copy .c file etc)  available.
Could we modify only snmpd.c as per requirement and cross compile  it ?
 
Thanks
