Help ! Subagent crash! (undefined symbol hosts_ctl , libwrap , libnetsnmpagent.so.5)

hey,
 
I've encountered some problems running the net-snmp tutorial example.
 
The problem:
------------------
- I have the Master agent running (with agentx enabled)
- I run the subagent from the tutorial (example-demon)
-  Wwhen I send a get request for the nstAgentSubagentObject, the
subagent crashes with error message:
  "symbol lookup error /usr/lib/libnetsnmpagent.so.5: undefined symbol:
hosts_ctl"
 
 
Analysis & solutions attempted:
-----------------------------------------------
- It seems that hosts_ctl is can be used only if the net-snmp if
compiled with flag USE_LIBWRAP
- I configured and built the net-snmp again with --with-libwrap
- I verified that USE_LIBWRAP is defined in
include/net-snmp/net-snmp-config.h
- and still I get the same problem !
 
 
any ideas?
----------------
 
 
Thanks,
Erez Makavy.
