Hello crowd,
I was in the process of writing an article about the YubiKey, and when I updated my local copy of yubico-pam I found out it wouldn't configure any longer.
It seems that ykpers-1 is now needed (for challenge-response apparently), and that check breaks the configure.
Of course, the solution was not so bad. One would have to install yubikey-personalization and then set PKG_CONFIG_PATH to include /usr/local/lib/pkgconfig, but I'm thinking this is the type of information that one would like to find in the README. At least it would have saved *me* some time
Cheers,
Le Coyote
