Leave all your root consoles open.  You won't be able to log in
until you fix PAM.  From your source:

"All the changes described have to be applied to each file in
the /etc/pam.d/ directory (the PAM configuration files). Please make
sure you remove eventual backup files (*~) before trying to update
sys-libs/pam, or the emerge process will fail as a safety measure.

As a safety device, the sys-libs/pam ebuild checks the files present
in /etc/pam.d/ for the now-deprecated modules, and stops the merge
process in case they are still used, to avoid locking you out of your
own system. "

All files in /etc/pam.d must be updated; if you unmerged PAM might
well have been the only version available:

Update the config files (as necessary - and remove backup copies) and
then remerge the package.
