No, the PYTHONPATH needs to be set by you. You can do that in the batch file 
which starts grass or you can do that in every python application. I also 
append the etc/python/grass.py application to the search path.

More info on the pythonpath env variable:
http://docs.python.org/using/cmdline.html?highlight=pythonpath#envvar-PYTHONPATH

I tend to do it in the python script because I have the feeling that this is 
more flexible than in the batch file.
