What steps will reproduce the problem?
1. easy_install WebOb
2. run a test suite --with-gae

What is the expected output? What do you see instead?

you get an error "module webob does not exist."  This is because "import
webob" was pre-loaded by noseGAE but its loaded path was in site-packages
so it gets ignored in the restricted import hook later.

I think this would be a typical problem because if you install WebTest with
easy_install it will install WebOb by default.  I was able to fix it by
deleting my global WebOb egg.

This was all using revision 25 (0.1.3a)

I can't reproduce this. I have webob installed in site packages via easy_install, and
I don't have any problems importing webtest or webob in test modules.

Does the nosegae self test pass for you? How about nosetests -v --with-gae in
support/helloworld?

yeah, still seems to be happening on my end.  Here's the exact error I get when
running tests in support/helloworld

if I remove
/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/WebOb-0.9.1-py2.5.egg
then it works

I'm surprised you aren't getting the same error because when I print out the
sys.path, I can see the problem.  All the GAE libs are getting appended when they
probably should be prepended.

Here is a patch that fixes it for me
