[Newb] Building 3.4

[sashan]

I built gcc-3.4 about a week ago. Then I did a cvs update and tried to 
rebuild again but it spat out this error.

In file included from /home/darkwing/Code/gcc_3.4_build/i686-pc-linux-gnu/libstdc++-v3/include/memory:55,
                 from ../../../../gcc_3.4/libstdc++-v3/src/allocator.cc:35:
/home/darkwing/Code/gcc_3.4_build/i686-pc-linux-gnu/libstdc++-v3/include/bits/allocator.h:52:31: bits/c++allocator.h: No such file or directory
In file included from /home/darkwing/Code/gcc_3.4_build/i686-pc-linux-gnu/libstdc++-v3/include/memory:55,

What am I doing wrong? 

Thanks.
