after reading the mailing list archives, I think my problem is the class loader.
here's the stack trace from the crash:
BUILD FAILED
No JAXP compliant XML parser found. See http://java.sun.com/xml for the
reference implementation.

this is typical. I tried the "move jaxp.jar and parser.jar to $JAVA_HOME/lib/ext" but
that did not fly. anyway, it looks like they load, if the trace includes
com.sun.xml.parser.Parser .
actually, I just now examined the ant.jar jarfile, and it seems to be corrupt, as my
jarfile browser hangs when I go to the UnknownElement class.
I'll look into this. it could be a decompression problem.
