>Description:
When updating audio/flac, I get the following error:
    => Checking file-check results for flac-1.5.0

>How-To-Repeat:
These two missing files are generated because the pandoc program has been found on the system:
    % which pandoc
    /usr/local/bin/pandoc
>Fix:
There is several strategies to fix this bug:
  1. Add converters/pandoc as build dependencies. The disadvantage of this strategy is that a tool with a lot of dependencies is needed to generate only two html files.
  2. Patch the CMakeLists.txt file to remove the section testing the presence of pandoc. The disadvantage of this strategy is the necessity of maintaining a patch.
  3. Patch the CMakeLists.txt file to add an additional USE_PANDOC option (which we could disable). The disadvantage of this strategy is that it involves additional development.

My personal preference would be for the third solution because the development time should not be too long and we could commit the patch upstream.
