I'm not really sure how your setup looks like. But we use
z3c.rml very sucessfull for the project Stephan wrote
the library for. 

But we still use reportlab 2.1 withthe newest z3c.rml release.

This looks like zope.interface isn't available in your sys path.

I think you need to review the c.buildout documentation and
try to setup a project. Probably take a look at zopeproject
I think available on PyPi.

I think it should be possible to write a script or use the
existing scripts in z3c.rml and use the z3c.recipe.dev:script
to generate a working starting point based on buildout for
running your PDF conversion script. At least buildout makes
sure that your packages are installed correct as working unit.

Also a good starting point is the READEM.txt file in 
the z3c.rml package. There are several tests which will
produce several PDF based on rml code.

No problem
