python-daff is compiled with python2 without good reason

[uswoods]

On my ArchLinux python(3) is default since years. Anyway the Makefile first demanded 3to2 and then compiled it with 3to2, but later installed installed it with the default python(3).

Executing the py2 code with py3 leads to a crash:

Traceback (most recent call last):

Thanks. The py2/py3 thing is awkward. If you are using the Makefile, then make py should work with python3 and not mess around with 3to2.

Hmm from the snippet you posted, it looks like an echo command in the Makefile is being expanded a bit differently for you than it is for me. That "\n\t" needs to end up being a newline followed by a tab.
