PYTHONPATH makes rebuild fail

[mstram]

  action@nodeh-131169:~/git/dnode(master)$      pwd                                                                                         
 /home/action/git/dnode                 

 npm install weak

Why is node-gyp trying to build stuff in the PYTHONPATH?

I.e. File "/home/action/git/SATK/tools/lang/parser.py" has nothing to do with 'npm install weak'

weak@0.3.3 install /home/action/git/dnode/node_modules/weak
node-gyp rebuild

When I set PYTHONPATH= (null), it works.
