So, here's the technical explanation:

It had nothing to do with the User-Agent but with the HTTP request 
headers that were sent.  By default CLI utilities such as wget and curl 
dont send any Accept-Encoding headers.  Server side we were sending a 
'Content-Encoding: gzip' header for the tar.gz file.  Since there was no 
'Accept-Encoding: gzip' header sent by the client, an uncompressed 
version was delivered to the client.  It's pretty inconvenient (as you 
noticed) to have a tar.gz file that is uncompressed.

I have removed the Content-Encoding header and replaced it with the 
correct Content-Type headers to identify the different download types.
