rake assets:precompile fails when there are erb files?

Hi,

I have a set of help pages that I want to put in the asset pipeline,
because I want to compile them once
and apply some erb changes to them.

I have them in a directory structure like this:
   app/assets/helppages
and have only one file, named h22.html.erb

When I try to precompile the assets, I get this error:

Did you ever get a solution on this? I’m encountering the same thing and trying to work it out.
