I'm attempting to inflate a zlib compressed file. Performing:

(InflateStream on: ((FileDirectory default fileNamed: 'filename')  
binary)) upToEnd

raises a bad block length error. John McIntosh's tiff support package  
in squeakmap contains zlib support, but it reports 'no installer  
found for package' (I'm using squeak 3.9.)

  Any recommendations for decompressing zlib files inside squeak?

Thanks, Brian.
