Answer 1

I think I had the same problem recently.
I installed the package by downloading the most recent tarball (the .tar.gz file PKI_0.1-5.tar.gz) from the PKI RForge page and then running
install.packages(<tarball_path>, repos = NULL, type = "source").
EDIT: Actually, it's easier to run install.packages('PKI',,'http://www.rforge.net/') as written in small print at the bottom of the PKI RForge page
EDIT2: Looking at the news, it looks like version 0.1-4 (perhaps more stable) also fixes the problem and, well enough, it works on my system, while 0.1-3 doesn't (the one on CRAN currently).
