Adding new hardware boards (cores)

[estratos 5]

I was trying to port all the panStamp NRG project done for Arduino IDE to Energia-1.6.10E18. I initially wanted to port it as a separate hardware under .energia15/packages/hardware/ so I simply copied the project from

./arduino15/packages/panstamp_nrg/hardware/msp430/1.0.7/

to

.energia15/packages/energia/hardware/panstamp_nrg/1.0.7/

The problem is that the boards listed in panstamp_nrg/1.0.7/boards.txt are not displayed under Energia->Tools->Board. Is adding new hardware cores disabled for Energia? Adding new variants under msp430/1.0.3/ works perfect.

Thanks for your time.
