You should do this using whatever account you logged in as; otherwise,
xauth will try to read /root/.Xauthority rather than
/home/whatever/.Xauthority.

No leading colon, but yeah, that looks right.

OK, looks like the second one was in fact right; it's not supposed to
yield any output.  Also, you'll find this command most effective if
you run it immediately after logging in, before starting PINE or
anything else.

Time for more background: every program has an environment, normally
inherited from its parent, which is a set of shared information
allowing for consistent yet variable behavior.  In particular, the
variable DISPLAY is a fairly universal means of specifying your
current X server.  Also, because environment inheritance essentially
takes the form of copying at program startup, setting the variable
after starting PINE won't affect anything run from within PINE.
