I installed linux_base-6.1 on my FreeBSD setup, but now X refuses to run! It 
starts spraying errors at random-- here's some of them ..

Authentication System Failure, muissing or mangled PAM configuration file or 
module?
Xwrapper: error reading PAM configuration file
pam_star: failed to initialize handlers
_X11TransSocketUNIXConnect: Can't connect: errno = 2

xinit: No such fiole or directory (errno 2): unable to connect to X server
xinit: no such process (errno 3): Server error.

I even tried pkg_delete'ing the linux_base package but no luck.
