sys.path issue in cygwin

[Wang Shuhao]

There is only python2.2.3 on my machine, and the location is /usr/local/lib/python2.2 . I say the 'C/lib/python2.2/' is a wrong path is because the leading C/lib is not point to the location of my python installation. I'v found the solution anyway. The environment variable PYTHONHOME controls the content of the initial sys.path. put 
export PYTHONHOME=/usr/local in .bash_profile will fix it.
