Use star drift in your eyepiece to correct alignment.
Do a rough polar alignment.
Use a star in the south sky at moderate elevation and center it in your
eyepiece, preferably with a crosshair, and with high magnification.
Now start following and see if the star drifts from the center.
Depending on what you use (say a zenithprism) the drift up or down
corresponds to an off setting to either the east or the west.
From the top of my head - with zenithprism: drift down more to the east
and drift up in your eyepiece move your mount more westward.
Please others here correct me if I'm wrong. And _if_ I am, you'll notice
soon enough and you have to reverse my instructions 
After you have adapted the mount, center again and start all oveer
again. A few stints and you have a fine alignment.
I had read about this in the telescope manual, but wasn't sure how
valid it was.
From what I could gather, what you are doing is using the error in the
tracking to correct your polar alignment. The manual actually has all
of the directions (up, down, left, and right) and how to correct.
I'll have to play with the geometry until I understand it.
It is the most accurate way of aligning your mount if done carefully. You
don't need a lot of accuracy for visual observing though.
