Is there a development system for the MSP430F series microcontrollers?
I use MSPgcc for msp430 series, IAR is another CSS The later have restrictions.
What chip are you trying to program or code for?

Edit- 
Uniarch mspgcc has been released, It supports newer msp430 chips and is now the preferred compiler over mspgcc4
Build directions for uniarch mspgcc
