Xscreensaver seems unable to use PAM on FreeBSD 11-BETA2

After recompiling the port with PAM support, i have been unable to get it to
use any form of pam authentication whatsoever

Enabling debug on the authentication method produces the following log

pam_fprintd.so fails in the same manner

All the other pam-aware applications work perfectly on my setup so i am
confident that the problem is in xscreensaver. It used to work on FreeBSD
10.3-RELEASE, however
