I am try to compile nutch from source for the first time, it is on a Mac running 10.5.6, and I just downloaded source, so it is a new copy.

And I get the following error:
[javac] /Users/jmartyniak/Projects/java/nutch-trunk/src/java/org/ apache/nutch/analysis/AnalyzerFactory.java:29: cannot access org.apache.hadoop.conf.Configuration [javac] bad class file: /Users/jmartyniak/Projects/java/nutch- trunk/lib/hadoop-0.19.0-core.jar(org/apache/hadoop/conf/ Configuration.class)
    [javac] class file has wrong version 50.0, should be 49.0
[javac] Please remove or make sure it appears in the correct subdirectory of the classpath.
    [javac] import org.apache.hadoop.conf.Configuration;
    [javac]                               ^
    [javac] 1 error


I ran the 'ant compile-core' target and got the above error.

Any ideas? I did some searching on google and didn't find anything really interesting, basically a bunch of instances where the same error was occurring in the nightly build.

Thanks in advance for the help.
