py-pytools @2012.1: build fails trying to use distribute

[mndavidoff (Monte Davidoff)]

I got an error building py27-pytools because it tries to use distribute instead of setuptools.

$ port installed py27-setuptools
The following ports are currently installed:
  py27-setuptools @0.7.4_0 (active)
$ sudo port -vs install py27-pytools

The attached patch works for me to fix the problem.

I can't reproduce this problem on my system now anymore. py*-setuptools was replaced by py*-distribute, I guess that solved the issue.

Thank you for your attention to this. As it says in the distribute documentation at ​​http://pythonhosted.org/distribute/, "Distribute is a deprecated fork of the Setuptools project. Since the Setuptools 0.7 release, Setuptools and Distribute have merged and Distribute is no longer being maintained." At one time, py*-setuptools was replaced by py*-distribute. More recently, this was undone, and py*-distribute was replaced by py*-setuptools. The py27-pytools install does not fail for me in the same way, probably because of fixes made to setuptools, but the build output shows it is not behaving correctly:

The MacPorts way is for MacPorts to manage downloads and dependencies, not the scripts for individual ports. This problem has been fixed upstream, and I've replaced the patch with one that upgrades to pytools 2013.5.6. (The setup.py.diff file is no longer needed.)
