problem appears to be fixed.  it was indeed a corrupted file, I assume due to my 
decompressor.

If anyone else has a similar problem with MacOS X public beta and ant, please tell 
them to go get a product called OpenUp from www.versiontracker.com . The utility that 
ships with the os has some problems with tar and gzip files, and may corrupt them.

please add this to the faq, and thanks for your before-the-fact help!
