Still doesn't work. Here is the exact set of commands :

[anguenot at dhcp-401-3751 tmp]$ echo $PYTHONPATH

[anguenot at dhcp-401-3751 tmp]$ svn co
svn+ssh://anguenot@svn.zope.org/repos/main/ZODB/trunk/ ZODB

[...]

Checked out external at revision 40348.

Checked out revision 40348.
[anguenot at dhcp-401-3751 tmp]$ cd ZODB/
[anguenot at dhcp-401-3751 ZODB]$ python setup.py build_ext -i

[...]

[anguenot at dhcp-401-3751 ZODB]$ python test.py -v
Running tests from src
Traceback (most recent call last):
  File "test.py", line 40, in ?
    from zope.testing import testrunner
ImportError: cannot import name testrunner
[anguenot at dhcp-401-3751 ZODB]$

Then if I'm adding the src dir within the PYTHONPATH it works :

[anguenot at dhcp-401-3751 ZODB]$ export PYTHONPATH=`pwd`/src
[anguenot at dhcp-401-3751 ZODB]$ echo $PYTHONPATH
/tmp/ZODB/src
[anguenot at dhcp-401-3751 ZODB]$ python test.py -v
Running tests from src
Running tests at level 1

[...]

I found the problem on my box. Twisted is installed on my Python version
and twisted requires zope.interface form Zope3 and this last was thus
installed on test Python I'm using to launch the ZODB tests.

within test.py the sys.path insertion looked like this one :

sys.path.append(src)

and then while looking for zope.testing.testrunner it couldn't be found
since the zope.interface doesn't include it.

I changed the test.py like below so that it append the src path first in
the list of dir the interpretor should look at.

sys.path.insert(0, path)

Checked in in rev [40349]

Cheers,

	J.
