Annotatrix pip-requirements failed to install

[GoogleCodeExporter]

What steps will reproduce the problem?
1.I followed the instructions to install annotatrix on this site 
http://sourceforge.net/p/apertium/svn/HEAD/tree/branches/apertium-annotatrix/web
/
2. However i was unable to fully install the language pair as sudo make install 
also gave me an error
3. I decided to move on, and run sudo pip3 install -r pip-requirements.txt in 
apertium-annotatrix/web

What is the expected output? What do you see instead?

I see this

tokenize;__file__='/tmp/pip_build_root/lxml/setup.py';exec(compile(getattr(token
