Hi Brian,

Here are some notes I made for myself about upgrading the bindings when
I upgrade Trac:

~ deleted the old svn and libsvn directories from

~ opened the python bindings .zip and copied the two directories
  to site-packages

~ copied all libsvn\_*.dll files to _*.pyd [1]

~ restarted the server and crossed fingers...

[1] I found this recommended in the t.e.o wiki at TracSubversion...

...in particular have you copied/renamed the .dll files? Hope this
