why oh why does the following with zfec-1.5.2 no longer work in a
sane fashion?

python setup.py install --root=$PATH

(python-2.7.14, python-setuptools-22.0.5, pyutil-3.1.0 installed,
this script used: https://pastebin.com/8D0YdBtj)

like it's done in all python buildscripts on SBo, gives with
zfec-1.5.2 this result (please note the UNKNOWN):

https://pastebin.com/4m8sV8Qa

needless to say, this borks tahoe-lafs, complaining about no zfec
>=1.10 is present.

any ideas?
