I believe that is due to github preventing people from hotlinking it.

Try curl -v https://raw.github.com/douglascrockford/JSON-js/master/json2.js

Ok, that makes sense. Will try to look into this.

Moving back to active for others to chime in. I'm running php 5.4.6 on ubuntu 12.10, so there may be others that can reproduce this. Looking at the initial report, for whatever reason, the js file is being seen as a tar archive, and that logic happens here: http://drupalcode.org/project/drush.git/blob/refs/heads/7.x-5.x:/include.... The mime type detection is highly dependent on local environment, and which packages are enabled for PHP, etc.

There's a bug in the logic that causes the file to be considered .tar

Other than that, it seems the OP has a poor php:

No fileinfo or mime_magic support available. [93.26 sec, 7.19 MB] [debug]

Committed attached patch.

Not much more to say here. Once the bug is corrected drush should work even without fileinfo.

@joelcollinsdc check that you have fileinfo enabled in your php.ini file:

extension=fileinfo.so
