Anisio,

Looks like the hadoop jars aren't on the CLASSPATH:

First, could you try:

$ ant test-libhdfs

and see if that works?

If it does, take a look at the the 'test-libhdfs' target in build.xml  
and see the various options and env. variables it passes to it the  
'make test' command being exec'ed.

In particular I think you are missing HADOOP_HOME ...
