During installation, continually running into this bad boy:
ImportError: /home/lights/Plone/buildout-cache/eggs/lxml-3.4.4-py2.7-linux-x86_64.egg/lxml/etree.so: undefined symbol: lzma_auto_decoder
Provide the full traceback.

This looks like a version mismatch problem between the "lxml" version distributed with Plone and some library installed in your system.
lzma_auto_decoder should be defined by the liblzma shared object. You can use objdump -tT to find out which symbols your version of liblzma defines. You must install one which defines lzma_auto_decoder (or use an lxml version fitting to your system).
