Note that the link to the pp software is for version 0.85_01 (which is a trial version and very old), and the most recent version (pp) doesn't have the --info flag.

There's a note in this entry in the Changes file that states that option was removed. Perhaps you could try installing a version that's less than version 1.018 where that change was introduced?

update: Here's a link to the 1.017 version tarball file that does contain the --info flag.
