Problems while building mspgcc

Hello,

I cloned the repositories for binutils and gcc from:
git://mspgcc.git.sourceforge.net/gitroot/mspgcc/binutils
git://mspgcc.git.sourceforge.net/gitroot/mspgcc/gcc

I find it more convenient to check out already patched code from the git
repository than download the original sources and patch them.

Then I switched to the last LTS Release: remotes/origin/lts/20120406

After that I did an out of source build of binutils using this configure
command:
 ../binutils/configure --target=msp430 --enable-languages=c
--program-prefix="msp430-" --prefix=/opt/mspgcc
("--enable-languages=c" does not seem to harm.)

The build went through smoothly and install succeded also.

I configured gcc with the same options to ../configure but when I tried
to compile I am stuck with this error:

---------------------------------------------------------------

What did I do wrong? I tried to find actual build instructions but
always stubled about quite outdated stuff.
Is there a build-script for the last LTS release around? Or an apt
repository for ubuntu?

Greetings,

Gunnar Henne
