Duplicity, amazon s3 backend exception
===

I'm trying to create an auto backup using duplicity into amazon s3 following this guide: [easy server backups to amazon s3 with duplicity][1]

However, at this command:

    duplicity /var/www s3+http://com.mycorp.myhost.backup

I encounter the error:

    BackendException: Could not initialize backend: No module named boot

Googling does not yield understandable results for me. FYI, the actual command I run is:

    duplicity /Users/okyretina/Dropbox/archive/ s3+http://com.sinkdrive.okyretina.dropbox.archieve

I understand that this guide is for linux and I am using mac osx lion but I figured it should work as well. Any help is appreciated. Thanks.
