PHP Guzzle - redeclare issue

Question

I'm using AWS .phar SDK to putObjects to S3. I'm using the same code on 3 other applications, but for some reason the latest one seems to fail.

Fatal error: Cannot redeclare class Guzzle\Service\Description\ServiceDescriptionInterface in phar

The above error makes no sense as: the "aws.phar" is only included once; guzzle was not installed to the server, there are no interfering namespaces.

Any idea?

Issue has been cleared.

Supposedly AWS's phar file needs to be in the same directory where AWS is declared. I.e. it uses sub class names relevant to their folder locations.
