You can also obtain the PPR source code by checking it out of CVS.
And here is the command for the unstable (2.xx) version:
cvs -z3 -d:pserver:anonymous@ppr.cvs.sourceforge.net:/cvsroot/ppr checkout -r BRANCH_2_0 ppr
Please keep in mind that major changes are going on in the development branch so it will have new bugs, undocumented incompatibilities, and may not even be buildable.
