I just sync'd to 1.328 and tried mvn clean install. Some investigation
led me to discover a problem finding apt. I am running mac os x
10.5.8, and I have been able to build in the past without this problem.

The workaround is:
$ cd $JAVA_HOME
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0 $ sudo ln -
s Home/bin bin

Here's the maven output:
655 ~/src/svn-fresh/yhudson/hudson/trunk $ mvn -e install -DskipTests
+ Error stacktraces are turned on.
