Make fails

[Matthew Daubenspeck]

Here is the error:

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]: *** [c-ares/Makefile] Error 1
make[1]: Leaving directory `/home/hobbit/hobbit-4.1.1/bbnet'
make: *** [bbnet-build] Error 2

The config.log is here:

http://daubnet.dyndns.org:3000/foo/config.log

I am trying to compile hobbit on a Debian Sarge server. Any suggestions?
I poked around the c-ares archives a bit and didn't really find anything
with the same error.
