Description of problem:
The packaging guidelines say that manual python byte compilation is possible in EPEL.

https://docs.fedoraproject.org/en-US/packaging-guidelines/Python_Appendix/#_manual_byte_compilation_for_fedora_29_or_earlier_including_epel

However, it doesn't work on EL6.

https://src.fedoraproject.org/rpms/python-rpm-macros/blob/el6/f/macros.pybytecompile#_24

python_version=$(%1 -c "import sys; sys.stdout.write('{0.major}{0.minor}'.format(sys.version_info))") \

$ python -c "import sys; sys.stdout.write('{0.major}{0.minor}'.format(sys.version_info))"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: 'tuple' object has no attribute 'major'

sys.version_info.{major,minor} doesn't exist in EL6's Python.  This is similar to bug 1369486.

Version-Release number of selected component (if applicable):
python-rpm-macros-3-14.el6.noarch

How reproducible:
always
