I found it in the FAQ on search.cpan.org. It's not the zipfile, but that they only index things that extract to a single subdirectory.

I got reports from PAUSE indicating that it works OK. One person had troble testing; said his version didn't like the lack of a top-level directory. Others PASSED, so that must have been fixed or fixed-up by the users. I've downloaded it OK so I know the zip is OK. That's the first thing PAUSE checks is that the archive format is readable and OK. It processed in a second or two and has been in my author directory.

As for the "standard" install, if they ever get it to work right on Windows... Apparently it is severely alergic to filenames with spaces in them, as it goes deep and isn't easy to fix. The normal place for installing is under \Program Files\... .

For a module that doesn't need any compiling, I use a "lite" approach since the only thing it needs to do is copy the file to the proper place. I don't know if non-Windows people support PPM.
