Is there any terminal tool to convert from ODT to PDF/PS?
On unoconv's gitHub page is stated that:


  LibreOffice 3.6.0.1 or later is required to use unoconv under MacOS X. This is the first version distributed with an internal python script that works.


There it's explained too, how to install it. 

And being the latest version of LibreOffice v4.0.1, there should be no problem with it.
