The
>>> import transaction
>>> transaction.__file__
resulted in (@ virtualev and globalenv):

The following things I did in the virtualenv, like you guys had proposed:
I just tried to do "python setup.py test", which failed with the same
import error as described above.
I therefore just reinstalled ZODB by "python setup.py install", then
launched "python setup.py test" again.
The second time, the test has been running and printing for several minutes:
It ended with:
..........
.....
Doctest: ZODB.tests.testblob.savepoint_isolation ... ok
Doctest: ZODB.tests.testblob.secure_blob_directory ... ok
testRedo (ZODB.tests.testblob.ClientStorageSharedBlobsBlobUndoTests) ... ok
testRedoOfCreation
(ZODB.tests.testblob.ClientStorageSharedBlobsBlobUndoTests) ... ok
testUndo (ZODB.tests.testblob.ClientStorageSharedBlobsBlobUndoTests) ... ok
testUndoAfterConsumption
(ZODB.tests.testblob.ClientStorageSharedBlobsBlobUndoTests) ... ok
testUndoWithoutPreviousVersion
(ZODB.tests.testblob.ClientStorageSharedBlobsBlobUndoTests) ... ok
----------------------------------------------------------------------
Ran 701 tests in 988.767s
OK
All this in the virtualenv!!!
Then, I was able to import ZODB for the first time:
(myproject)tyan at tyan-desktop:/media/daten/tyan/blast-tyan16x/External_Tools/ZODB3-3.10.5$
python
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ZODB
>>> quit()
(myproject)tyan at tyan-desktop:/media/daten/tyan/blast-tyan16x/External_Tools/ZODB3-3.10.5$
But, when I switch to globalenv (real system path) again, I still get
the import errors:

:(
Any further ideas?
Python path is set in the global environment. In the virtualenv, it was
not set, but everything worked there anyway.
Best regards,
Ralf
