converters/TECkit - dynamically generated tar file fails checksum

[Chuck Cranor <chuck%ece.cmu.edu@localhost>]

hi-

    looks like the default source site for converters/TECkit is dynamically 
generating the tar.gz file we are downloading, causing the gz timestamp 
to change with each download.   this makes the build fail with a checksum
error.

    what is the correct way to fix this?
