Oh yes, it is a bit late at us now, so I have missed it.
Copying the GCC compiler template, and correcting the executables path does not working, because the mspgcc has several compiler specific option just like the -mmcu option for e.g.
I have checked out the latest code, and found the related code in the compilerGNUMSP430.cpp. As I seen it is not windows only, and it is looking for the executables in the /usr/local/msp430. I have linked the neccessary content to there.
I have analyzed the code further and realized that this compiler is not enabled on Linux.
So I will hack it tomorrow.
