The map shows up, but the Line I draw is no where to be found on the map, and the mouse position control seems to be showing lon/lat values, but somewhat off by a few degrees.
It appears to be a mismatch of things somewhere, but I haven't been able to figure it out. Thanks for your help.
I find that reprojection is a lot more accurate if I preload proj4js. OL will auto-detect this and use it. I don't know how OL does them if you don't use proj4js; check the source code if you're interested.
You would download the proj4js files and unpack them on your server, then include them like this. Do this BEFORE your <script> tag which loads OpenLayers.js
