You are running into an issue caused by a change in setuptools:

https://github.com/pypa/setuptools/issues/1934

It looks like the simplest solution is to first install the wheel
package in your venv:

pip install wheel
pip install flask-mongoengine==0.9.5

Either that or install a previous version of setuptools.  You may want 
to chime in on the discussion of that issue.
