Hey Chris, Thanks for reporting. I filed HDFS-790 and uploaded a patch (which you will need to apply after applying HADOOP-5611) and verified it compiles on karmic 64-bit. In the mean time if you just need to build libhdfs (which doesn't depend on c++-utils) you can do that with ant -Dcompile.c++=true -Dlibhdfs=true compile-c++-libhdfs. Lemme know if you hit any other issues.
Thanks, Eli
