Mac version: corrupted database - restore fails

Was wondering if anyone could offer some advice or things to try to get my database working again. I recently switched machines and moved everything over using Carbon Copy Cloner.

Now when I try to launch Calibre I get the database corrupted error. When I try to run calibredb restore_database I get the following mysterious output:

Code:
➜  MacOS  ./calibredb restore_database -r
Failed to parse options string:

Anyone have any idea what I might try to get this working?

delete the metadata.db file (back it up first). Then start calibre, calibre will create an empty metadata.db, then follow the instructions here: http://manual.calibre-ebook.com/faq....n-app-is-blank

Alternately, pass the --with-library option to calibredb restore_database since that erro ris coming from an inability to read the stored database path in a corrupted config file.
