This is due to the current working directory being set to Blender's
directory, and not the directory of the .blend file.

Loading your script as an add-on gives the added advantage that you
can press F8 to reload it. However, usually I want to put my .blend
file and Python scripts in the same directory. If you want to do that
too, take a look at the approach I describe at
http://stuvel.eu/blog/203/reloading-your-code-in-blender This gives
you a setup that allows you to load modules from the same directory as
your .blend file, and easily reload your code. The reloading isn't
flawless, but it works most of the time ;-)
