How to install lxml and pycurl in Virtualenv?

Question

Django

Good afternoon!
I ran into an error when trying to install lxml and pycurl in a virtual environment (Virtualenv) using python3.4. I looked through many forums but the suggested solutions did not help.
Using Ubuntu 14.04.4 LTS
The error itself looks like this (tried using pip and easy_install)

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
    ----------------------------------------
Command "/var/virtual/python3.4/bin/python3.4 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-fyqky764/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-64zf48ta-record/install-record.txt --single-version-externally-managed --compile --install-headers /var/virtual/python3.4/include/site/python3.4/lxml" failed with error code 1 in /tmp/pip-build-fyqky764/lxml/
