py-stevedore @0.8: broken by distribute 0.7.2

[macports1@…]

The latest update to py27-distribute which deprecates itself and installs py27-setuptools @0.7.2_0 breaks the py27-stevedore package.

When stevedore package is loaded, the following error is shown:

stevedore.extension Could not load 'user_scripts': distribute
stevedore.extension distribute
Traceback (most recent call last):

The Priority field is for MacPorts committers; please do not set it.

I just installed py27-stevedore, and import stevedore works fine. Try reinstalling it.

% sudo port -n upgrade --force py27-stevedore

[macports1@…]

Sorry for the priority set.

I did try to upgrade stevedore package but it didn't fix the error. I had to reinstall the py27-distribute @0.6.45_0 back to avoid the error above. I will find how to reproduce it because the error above is thrown while I execute my dotfiles. For some reason it tries to load 'distribute' dynamically.

[macports1@…]

To reproduce the error you should:

1. install py27-virtualenvwrapper @4.0_0

2. create a folder $HOME/Env

3. make sure virtualenv27 is selected:

sudo port select virtualenv virtualenv27

4. add to your bash_profile:

export WORKON_HOME=$HOME/Env
source /opt/local/bin/virtualenvwrapper.sh-2.7

5. Execute your terminal again.

I think virtualenvwrapper @4.0_0 depends on distribute, but I might be wrong.

Cc-ing the virtualenv maintainer. You don’t have to Cc yourself because you’re the ticket reporter.

[jmroot (Joshua Root)]

You would need to use -s to ensure a rebuild actually happens, i.e.:

% sudo port -sn upgrade --force py27-stevedore

So are you saying the problem only happens when virtualenvwrapper is used?

[macports1@…]

Yes, that's right. It happens only when I call virtualenvwrapper init, the "source /opt/local/bin/virtualenvwrapper.sh-2.7" in the bash_profile.

I'm seeing a similar problem with stevedore and distribute when I try to install py27-stevedore (main.log is attached):

The attached patch (Portfile.diff, setup.py.diff) works for me to fix the build problem and the originally reported problem using virtualenvwrapper.
