lxml installation error ubuntu 14.04 (internal compiler error)
Possible solution (if you have no ability to increase memory on that machine) is to add swap file.
sudo dd if=/dev/zero of=/swapfile bs=1024 count=524288sudo chmod 600 /swapfilesudo mkswap /swapfilesudo swapon /swapfile

This worked for me on smallest digital ocean machine
In this particular case, it has nothing to do with dependencies, it's a memory problem.
I had this problem within a virtualbox VM. My solution was to increase memory allocated to the VM from the default 512Mb to 1024Mb.

Go install some dev packages before pip install lxml
apt-get install libxml2-dev libxslt1-dev python-dev
