Wrong python version is used to run setup.py

I am trying to package a Python 2-only tool, qiime. I'm getting the following error:

% pyp2rpm -s qiime -b 2  
INFO  Pyp2rpm initialized.
INFO  Using /home/feuerbach/rpmbuild/SOURCES as directory to save source.
INFO  Downloaded package from PyPI: /home/feuerbach/rpmbuild/SOURCES/qiime-1.9.1.tar.gz.

SyntaxError: invalid syntax

I may be completely off here, but it seems to me that the error is caused by setup.py being run with Python 3, not Python 2, even though I requested only a Python 2 build.

% rpm -q pyp2rpm 
pyp2rpm-3.1.2-1.fc24.noarch

The same problem has been reported before #47.
