Hi Stephan,
It looks like you now have V3 firmware, which requires using the TI
MSP430 library via the "tilib" driver. You can downgrade to V2 again
by following the instructions here:
http://processors.wiki.ti.com/index.php/MSP_Debug_Stack
Otherwise, if you're willing to wait, I'll be putting together some
patches for building the library on Linux sometime this week.
Cheers,
Daniel
