установить lxml

подскажите пожалуйста как установить библиотеку lxml в linux mint

я деалю следующее: в .profile добавляю: 

export WORKON_HOME=$HOME/.virtualenvs/moda_project
export PROJECT_HOME=$HOME/.virtualenvs/moda_project/moda

не забываю сделать: 

source .profile

затем активирую виртуальное окружение и в соответствии с этим выполняю в консоли: 

pip install lxml

в результате получаю следующее сообщение(привожу только последний фрагмент): 

copying src/lxml/isoschematron/resources/xsl/iso-schematron-xslt1/iso_schematron_skeleton_for_xslt1.xsl -> build/lib.linux-x86_64-3.4/lxml/isoschematron/resources/xsl/iso-schematron-xslt1

On Linux (and most other well-behaved operating systems), pip will manage to build the source distribution as long as libxml2 and libxslt are properly installed, including development packages, i.e. header files, etc. Use your package management tool to look for packages like libxml2-dev or libxslt-devel if the build fails, and make sure they are installed. Alternatively, setting STATIC_DEPS=true will download and build both libraries automatically.

Установка python-lxml уже дает возможность использовать lxml в python'е. Но в то же время она (установка python-lxml) не является достаточным условием для установки lxml из pip'а.
