Problem with Trac and Python

[jc@…]

I know that there already were a similar problem but i tested all solutions adviced on your site.

My problem is to access svn with trac. When i read the trac's log, i've the following lines :

Trac[svn_fs] INFO: Failed to load Subversion bindings
Traceback (most recent call last):
  File "build/bdist.macosx-10.5-i386/egg/trac/versioncontrol/svn_fs.py", line 265, in __init__
    _import_svn()

    import _fs

  Referenced from: /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/libsvn/_fs.so
  Reason: image not found

My system : Mac OSX 10.5.8 with Python 2.5.1 and Subversion 1.6.16

I tried the followings :

sudo port install python_select
sudo python_select python25
sudo port install subversion-python25bindings

and nothing works. With this, i've an Internal Server Error.

Best regards,
