You don't have the TinyOS distribution of the MSP430 toolchain (or  
it's using another installation).

When nesC generates a C file for the native C compiler, it uses $ in  
its name-mangling to make sure that C can't work around component  
encapsulation. The GNU assemblers don't allow this by default, but  
have a simple compile-time flag to allow it. So the TinyOS  
distributions are just the standard source trees with the $ option set.
