How to integrate "KPIT GNURX [ELF] Toolchain" into HEW environment integrated with Standard RX tool chains already?

Hello my dear friends,
I'm working with the RSKRX62T(RX62T Renesas Starter Kit) and HEW Version 4.09.01.007,
The sample code is :
RX62T Renesas Starter Kit Sample Code for High-performance Embedded Workshop with GNU RX Compiler.
However, building phase was fail,
My HEW environment is integrated with Standard RX tool chains,
After I copied the sample code to my workspace, then build it,
the following message comes as below:

'KPIT GNURX [ELF] Toolchain', version 'V12.03' is missing from the following project(s)
CAN
Sync_Serial
ADC10_Repeat
LVD
WDT
ADC10_Oneshot
IIC_Master
ADC12_Oneshot
Timer_Compare
Power_Down
DTC
Async_Serial
Flash_Data
IIC_Salve
PWM
LIN_Master
Timer_Capture
Timer_Mode
ADC12_Repeat
CRC
IWDT

There is no compatible toolchain. Build functionality will not be available.

My Question:
How to integrate "KPIT GNURX [ELF] Toolchain" into HEW environment integrated with Standard RX tool chains already?

Can anyone help me on this?
