debian/patches/_metaphlan2.py.patch

+Author: Tony Travis <tony.travis@minke-informatics.co.uk>
+Las-Update: Mon, 28 May 2018 01:36:48 +0100
+Origin: https://lists.debian.org/debian-med/2018/05/msg00071.html
+Description: Compile with Python2 despite _metaphlan2.py is using Python3 syntax
+ The "_metaphlan2.py" file contains Python 3 source but the "postinst"
+ script runs "pycompile" on the Python source files. However, "pycompile"
+ only supports Python version 2. The print() function in "_metaphlan2.py"
+ can be imported from the "__future__" library, but Python 2 does not
+ support function annotations: These are optional in Python 3, and are
+ removed from the function definitions in "_metaphlan2.py" by the patch.
