Oh system Pythons.
I can only reproduce this using the ubuntu python-setuptools
package. Installing setuptools myself using ez_setup doesn't give
this behavior.
The Unbuntu python-setuptools package installation is rather odd. It
doesn't install setuptools as a normal egg. Rather it installs it in
such a way that it shows up as a develop egg.
[EMAIL PROTECTED]:~/tmp$ python
Python 2.5.1 (r251:54863, May 2 2007, 16:56:35)
[GCC 4.1.2 (Ubuntu 4.1.2-0ubuntu4)] on linux2
Type "help", "copyright", "credits" or "license" for more
information.
>>> import pkg_resources
>>> pkg_resources.working_set.find(pkg_resources.Requirement.parse
('setuptools'))
setuptools 0.6c5 (/usr/lib/python2.5/site-packages)
Note that the location of the setuptools egg is site packages.
>>> d = pkg_resources.working_set.find
(pkg_resources.Requirement.parse('setuptools'))
>>> d.precedence == pkg_resources.DEVELOP_DIST
True
So, the Ubuntu packager for setuptools decided not to install
setuptools as an actual egg, but as a wonky sort-of develop egg with
a less than ideal location.
IMO, this is just wrong and broken. Does anyone disagree? I could
probably add logic to the bootstrap script to get around this, but
I'm not very motivated to do so. I'm inclined to say that if you
choose to use this version of setuptools, by using your system Python
and a system package of setuptools, then you'll have to live with its
limitations.
Of course, your system easy_install won't install routs either:

a more recent version first.

The good news is that setuptools can repair itself:
sudo easy_install -U setuptools
Doing this causes setuptools to upgrade itself to a regular egg-based
install. At this point (at least on my system), I can install routes
and, when I run buildout, it doesn't create an egg link in the develo-
eggs directory. Of course, at that point, you've probably messed up
your system packaging
I will probably do something about this in the long run though just
to avoid the question coming up.
