Broken link for index.html

I tried to build static htmls by using the "forrest site" command.
For some files I get the following error message:

-> [broken page] methods/gl_design/index.html <-

     input-modules: ComponentSelector could not find the component
      for hint [conf] (key [conf])

In the source-tree, the respective xml-files are present.
I use the cvs-version of forrest, last updated today morning (CEST).
Did I miss something (I didn't work with forrest the last few days) ?
What's going wrong ?

TIA,
Stephan
