I've been using the python-nltk package on Ubuntu, but I need ntlk 3.0 now. I used 'sudo aptitude purge python-nltk' to get rid of my existing installation, & followed instructions on the nltk website [1] starting at step 4 (since I already have python-pip & python-numpy packages installed).
$ sudo pip install -U I couldn't get it to work, until I realized that the permissions & ownership on /usr/local/lib/python2.7/dist-packages were 'drwx--S--- root staff'. A 'chmod -R a+rX' on that directory seems to have fixed it. Is it normal for sudo pip install to set the permissions that way, or did I do something wrong?
