with the install crossdev from my overlay and then :
crossdev -t msp430
at one point it will stop and warn you to run some script. It will setup some 
links such that gcc will find binutils stuff, the stable msp430-gcc is really 
old...

binutils is a separate package, the gentoo  patchset for binutils includes 
this patch already ( version binutils-2.16.*  only ) 
( see  
http://sources.gentoo.org/viewcvs.py/gentoo/src/patchsets/binutils/2.16.1/ )
mspgcc does not needs this patch
