This looks like you're using Python 3.2 to run Pyflakes on a source tree
that was written for Python 2.x.
u'unicode string literals' are invalid syntax on Python 3.0 through 3.2.
Perhaps the error would be a bit clearer if the caret pointed to the
beginning of the string literal, instead of the end.

Well, it is unused. You're merely importing it for the side effects
(which is, generally speaking, a Bad Idea).
In my pyflakes fork (which I intend to upstream Some Day Real Soon Now)
I made pyflakes ignore unused imports if there's a comment on the line,
with the intent that the comment explain why this unused import is here.
E.g.
import dslrpicontrol.loggers # for the side effects
It doesn't look immediately upstreamable:

since it depends on my earlier changes that added command-line warning
filtering:
