Hi vamank,

My bad - I've changed the set up a little.
The missing file(s) used to get installed as part of the Audio::Scan install, but now they're installed separately. Just run:

ppm install http://www.sisyphusion.tk/ppm/PPM-Sisyphusion.ppd
[download]

and that should be all that's needed.
The Audio::Scan ppd file does specify PPM-Siyphusion as a prerequisite, but I guess that the use of --force means that the absence of that prerequisite can be ignored.

With the new (undocumented) set up, the idea is that you add the sisyphusion repo to your list of repositories:

ppm repo add http://www.sisyphusion.tk/ppm
[download]

and then install the desired module with:

ppm install http://www.sisyphusion.tk/ppm/Audio-Scan.ppd
[download]

And that should install the module, along with any missing prerequisites.
However, there are still some packages there (namely, the ones that don't provide for perl version 5.26) that might still require --force.
You can check the full list of available modules, along with the versions of perl that they each cater for, at http://www.sisyphusion.tk/ppmindex.html.

Sorry for the mess.

Cheers,
Rob
