wget has the --user-agent=agent-string (or -U for short) flag that
lets you pretend to be a browser.  The program file tells the type.

0806.3141v2: gzip compressed data, was "0806.3141.tar", from Unix, last modified: Thu Mar 26 22:29:50 2009, max compression

Also, curl - similar to wget but part of OS X - works directly.

Note:  arxiv has this tendency to provide files without the type.  I
suggested to them that the PDFs they download ought to have '.pdf' on
them and eventually they switched (no acknowledgment to me though). 
This looks like the same thing - we all should "independently"
complain about it ...
