> When I add a new dependency that needs to be downloaded (this started with 
> downloading ant from ibiblio and continued with jars from download.java.net), 
> the download will fail with a "negative argument" message if I use a shell 
> inside of emacs.  If I use Terminal.app or an Emacs term (which has full 
> terminal capability), the download works fine.
> You can see the trace of the failure at http://pastebin.com/u75s31jq
> I'm fairly certain that wget is exploding for some reason when it tries to 
> put up its progress bar and the terminal doesn't support it.  If I run wget 
> directly from the shell, the file downloads fine, so it is related to how 
> wget is called from buildr.
> buildr runs fine in an emacs shell if it does not need to download a new 
> dependency.
