trying to use the latest grok version on Mac OS X, I get some errors. First I create a virtualenv and install grokproject like this:
virtualenv --no-site-packages testEnv
That works fine so far. Then I try to create a project like this
an get the following error message:
Running /Users/domma/Develop/GrokProjects/testEnv/bin/python -S /Users/domma/Develop/GrokProjects/testEnv/Sample/bootstrap.py...
Traceback (most recent call last):
File "/Users/domma/Develop/GrokProjects/testEnv/Sample/bootstrap.py", line 21, in <module>

ImportError: No module named shutil
/bin/sh: /Users/domma/Develop/GrokProjects/testEnv/Sample/bin/buildout: No such file or directory
If I execute python by hand, shutil is available. So I guessed that the -S flag must be related to the problem and I tried the following:
I get the following warning, but the script seems to do it's job:
/private/var/folders/Zr/Zr383cMLG1q36K2WKIjjQE+++TI/-Tmp-/tmpVzOWT0/zc.buildout-1.5.2-py2.6.egg/zc/buildout/buildout.py:303: UserWarning: Buildout has been asked to exclude or limit site-packages so that builds can be repeatable when using a system Python. However, the chosen Python executable has a broken implementation of -S (see https://bugs.launchpad.net/virtualenv/+bug/572545 for an example problem) and this breaks buildout's ability to isolate site-packages. If the executable already has a clean site-packages (e.g., using virtualenv's ``--no-site-packages`` option) you may be getting equivalent repeatability. To silence this warning, use the -s argument to the buildout script. Alternatively, use a Python executable with a working -S (such as a standard Python binary).

After that I execute
and am able to start the server afterwards. So everything seems to be working now, but not as smooth as expected. Don't know if it's problem with my system or a general problem related to OS X. Any hint how to fix/debug it? Not being a Grok/Zope expert, I would feel better having a system which is known to be working correctly and as described in the documentation. ;-)
