Bug#800668: iep ftbfs, missing build dependencies, still fails tests

[Ghislain Vaillant]

Hi Matthias,

The setup.py only lists pyzolib as install_requires, not setup_requires. 
Therefore, I assumed they were not intended to be installed at build time.

I am also not quite sure whether this package has an official test 
suite, so unittest.discover may be picking something which was 
unintended to be picked.

I can make a new upload with an explicit empty test target, will it 
solve your issue?

Many thanks for reporting this,

Ghis
