build SID fail....

Hi all:

I'm trying to build the SID on the CVS in my Ubuntu 6.06.
While I did the make operation, I got the following message...

checking whether c++ accepts -g... no
checking dependency style of c++... none
checking how to run the C++ preprocessor... /lib/cpp
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.
make[1]: *** [configure-sid] Error 1
make[1]: Leaving directory `/home/s88/work/sid/sid-cvs/build'
make: *** [all] Error 2

I have tried the gcc-2.95 and gcc-3.4, but all of them show this message...
How could I slove this problem?!!

Thanks.

Dave.
