Dear Assa,
this is a quantum-espresso question, rather than wannier (not to mention
want, that is a different project).
If you search the archives in pw_forum, you'll find it discussed
extensively, but it should not be a problem, if the code does not
stop with an error.
Note that the xauth message is unrelated, and not an error at all.
