Build of ORO Regex package fails

Hi,
I downloaded ORO-Regex yesterday and tried to build it with the included
batch. It did not work, and I got the message:

BUILD FAILED

The AElfred parser is a SAX2 XMLReader

The things I tried were to remove the jaxp Parser I use from the classpath,
but that did not help. I have installed SAXON as well, might that be the
reason for my problems?

Thanks for answering, 

Best regards
