If somebody could help me I would really appreciate it! I have a suspicion that the issue has to do with multiple versions of python but I'm not sure how to check or fix that.

Set up a virtualenv:
% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py
% sudo python /tmp/get-pip.py
These commands install pip into the global site-packages directory.
% sudo pip install virtualenv
and ditto for virtualenv:
% mkdir -p ~/.virtualenvs
I like my virtualenvs under one tree in my home directory called .virtualenvs
% virtualenv ~/.virtualenvs/lxmltest
Creates a virtualenv.
% . ~/.virtualenvs/lxmltest/bin/activate
Removes the need to specify the full path to pip/python in this virtualenv.
% pip install lxml
Alternatively execute ~/.virtualenvs/lxmltest/bin/pip install lxml if you chose not to follow the previous step. Note, I'm not sure how far along you are, so some of these steps can be safely skipped. Of course, if you mess something up, you can always rm -Rf ~/.virtualenvs/lxmltest and start again from a new virtualenv.
It looks like you're having a permissions error, based on this message in your output: error: could not create '/lib/python2.7/site-packages/lxml': Permission denied.
One thing you can try is doing a user install of the package with pip install lxml --user. For more information on how that works, check out this StackOverflow answer. (Thanks to Ishaan Taylor for the suggestion)
You can also run pip install as a superuser with sudo pip install lxml but it is not generally a good idea because it can cause issues with your system-level packages.
On a Mac, you need to use this command:
STATIC_DEPS=true sudo pip install lxml
