using 
python 2.4.5
Zope 2.11.1-final
DirectoryStorage 1.1.19

First, is there a more preferable product to use to serve files, mostly PDF, 
from the file system with Zope?  

I suspect lock_file.py has changed since the DirectoryStorage product was last 
updated.

I followed instructions on http://dirstorage.sourceforge.net/install.html to 
install DirectoryStorage.  I got to step 11. "Start Zope"
and at the end of Traceback 1 (see below)
  File 
"/usr/local/lib/python2.4/site-packages/DirectoryStorage/PosixFilesystem.py", 
line 12, in ?
    from ZODB.lock_file import lock_file
ImportError: cannot import name lock_file

There are no classes or methods named lock_file in lock_file.py so I changed 
the import statement in PosixFilesystem.py to 
from ZODB import lock_file

Then the same thing occured in BaseDirectoryStorage.py and I made the same 
change to that import statement. (see Traceback 2)

Now (see Traceback 3) I get   File 
"/usr/local/lib/python2.4/site-packages/DirectoryStorage/LocalFilesystem.py", 
line 55, in engage
    raise DirectoryStorageError('Storage is locked by another process')
DirectoryStorage.utils.DirectoryStorageError: Storage is locked by another 
process

But I'm not sure how to overcome this or is this because the locK_file problem 
but I suspect so. I can't find anything 
that indicates Storage is locked except for the end of that traceback.

I don't know if I need to do " from ZODB.lock_file import _lock_file " or 
something else.

Any help would be appreciated.

Thanks,

Thomas
