cross compiled snmpd is not responding

Hi all, 
I have to to rum  net-snmp on a powerpc board. The direct compilation on  board gives a fairly respondimg snmpd but when I cross-compile the same on a FC4 machine for powerpc target , the compilation is successful , but the  cross compiled snmpd daemon is not responding to the snmp queries.

Cross-compiler I am using is 	
powerpc-750-linux- (upwind/gnuwing)

Host Machine is 
Linux 2.6.16-1.2096_FC4 i686 i386 GNU/Linux

The snippet for cross-compilation of snmp in my compilation script in following

--------snippet start------------------------------------
export TOP_DIR=(cvs_source_root_path)
export SNMPD_DIR=$TOP_DIR/AGNi/SNMP/SNMPDmn
export CUR_DIR=$PWD
cd $SNMPD_DIR
$SNMPD_DIR/configure --host=powerpc-750-linux-gnu --with-ar=powerpc-750-linux-gnu-ar --with-ranlib=powerpc-750-linux-gnu-ranlib --with-ld=powerpc-750-linux-gnu-ld --prefix=$TOP_DIR/mfp/snmp --with-endianness=big
make
make install
cd $CUR_DIR
--------snippet end---------------------------------------

The behaviour of the compiled snmpd is strange. For any localhost/client query, it doesn't respond at all.
On the board, I am forking the snmpd daemon in one of my parent processes as:

-------snippet start--------------------------------------

int StartSNMPD ()
{
    pid_t pid;
    char *arg[] = {"snmpd", "-Lsd -Lf /dev/null -p /var/run/snmpd -a -c /mfp/snmp/share/snmp/snmpd.conf -C", (char *) 0 };
    char dpath[20];

    strcpy ( dpath, EBX_BIN_PATH ) ;
    strcat( dpath, "/snmpd")  ;
    printf ( "\nsnmpd path is : %s\n" , dpath ) ;

    if ( (pid=fork()) < 0)
	{
        	perror("fork()-->");
	        return ERROR;
        }
    else if(pid != 0)
	{
        	waitpid(pid,NULL,0);
        }
    else if(pid == 0)
	{
        	execv ( dpath, arg);
	        return OK;
        }
    return 0;
}


--------snippet end---------------------------------------



Plz help.
