py27-pylint @1.0.0: Destroot failure

Running Macports 2.2.0 on OS X 10.6.8 with Xcode 3.2.6. Attempting to install py27-pylint gives the following error:

Reassigning to stromnov@…, I'm not taking on an issue from an upgrade I didn't do ;)

[stromnov (Andrey Stromnov)]

Can't reproduce. Looks like broken distutils/setuptools chain.

Please provide output of:

python2.7 -c "import sys, pprint; pprint.pprint(sys.path)"

and

echo $PYTHONNPATH

[mark.chilenski@…]

Here are the requested outputs:

$ python2.7 -c "import sys, pprint; pprint.pprint(sys.path)"

Please advise for how to rectify this situation, thanks!

It' s very interesting, is it a problem only with your system, or somebody have similar problems?

Probably (but I'm not sure), yours custom packages interfere with macports distutils/setuptools.

You have several non-macports packages, such as scikits.bootstrap-0.2dev, MDSplus-4.0_2 and infpy-0.4.11 installed globally (probably via sudo pip-2.7 install).

You can uninstall python27 with all py27-* packages, ensure, that '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/' is empty, and then reinstall python27 with py27-pylint.

I was able to solve the problem by removing what is apparently an interfering version of setuptools in site-packages, no need to remove python27 and py27-*. The ticket may now be closed, thanks for the help!

For others' reference with similar issues, here are the details of what I did:

I tried uninstalling all three of the non-Macports packages (sudo pip-2.7 uninstall <NAME>) and it did not work.

I then tried uninstalling and reinstalling py27-setuptools (sudo port -f uninstall py27-setuptools followed by sudo port install py27-setuptools). py27-pylint still failed to install.

I then noticed that there were several redundant files in site-packages associated with setuptools:

drwxr-xr-x   35 root  wheel    1190 Aug 31 13:07 setuptools
drwxr-xr-x    3 root  wheel     102 Jun 19 15:12 setuptools-0.7.2-py2.7.egg-info
drwxr-xr-x    9 root  wheel     306 Jun 11 14:42 setuptools-0.7.2-py2.7.egg-info.OLD.1371669160.36
drwxr-xr-x    9 root  wheel     306 Aug 31 13:07 setuptools-1.1-py2.7.egg-info
drwxr-xr-x   30 root  wheel    1020 Jun 11 14:42 setuptools.OLD.1371669160.36

I verified that 1.1 is the active version in Macports and that all inactive ports had been uninstalled (sudo port -f uninstall inactive -- an overkill approach, I know), and yet all of those files remained.

So, I deleted the old directories one-by-one, testing after each deletion. py27-pylint finally installed when it was just setuptools and setuptools-1.1-py2.7.egg-info left.
