scons reports "UserWarning: Unbuilt egg for setuptools..."

[Ingo Ruhnke]

Binary package hint: scons

Running a simple empty SConstruct file with scons leads to:

/usr/bin/scons:169: UserWarning: Unbuilt egg for setuptools [unknown version] (/usr/lib/python2.6/dist-packages)
  d = pkg_resources.get_distribution('scons')

Which probably indicates a problem with the scons package.

Full way to reproduce the problem:

$ touch SConstruct
$ scons
/usr/bin/scons:169: UserWarning: Unbuilt egg for setuptools [unknown version] (/usr/lib/python2.6/dist-packages)
  d = pkg_resources.get_distribution('scons')
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: `.' is up to date.
scons: done building targets.

Not an scons issue it seems, the bug is already documented at:

https://bugs.launchpad.net/ubuntu/+source/distribute/+bug/576434

The workaround given there, namely:

sudo rmdir /usr/lib/python2.6/dist-packages/setuptools.egg-info
sudo apt-get install --reinstall python-setuptools

Solved the issue for me.
