ViewCVS and Subversion

I've seen several posts about ViewCVS and Subversion, but I haven't been 
able to get ViewCVS here at work to talk to our Subversion repository.  
When I try to access ViewCVS, I get the following error:


An Exception Has Occurred
Python Traceback
Traceback (most recent call last):
File "/data/www/admin/viewcvs/lib/viewcvs.py", line 2468, in main
request.run_viewcvs()
File "/data/www/admin/viewcvs/lib/viewcvs.py", line 256, in run_viewcvs
import vclib.svn
File "/data/www/admin/viewcvs/lib/vclib/svn/__init__.py", line 27, in ?
from svn import fs, repos, core, delta
ImportError: No module named svn


I Googled this error and found the following post (to this mailing list):

http://mailman.lyra.org/pipermail/viewcvs/2003q1/001734.html

The poster recommends installing Swig 1.3.16 or greater (I checked, we 
have 1.3.19 installed), and compiling Subversion SWIG Python bindings, 
which I told configure to do.  When I built Subversion, I used the 
following configure string:

./configure --with-apxs="/opt/apache2/bin/apxs" --with-ssl 
--prefix="/opt/subversion" \
   --enable-swig-bindings=python

Doing "find /opt/subversion | grep py" yields:

/opt/subversion/lib/libsvn_swig_py-1.so.0.0.0
/opt/subversion/lib/libsvn_swig_py-1.so.0
/opt/subversion/lib/libsvn_swig_py-1.so
/opt/subversion/lib/libsvn_swig_py-1.la
/opt/subversion/lib/libsvn_swig_py-1.a

...so it's obvious that some Swig/Python-related libraries are being 
built.  But curiously enough I don't see any actual ".py" files, which I 
assume are necessary for the python bindings to be seen by python 
applicaton.  They can't just read .so files directly, right?  I may be 
incorrect in this assumption (I'm not well-versed in Python).

I also thought that maybe installing Subversion to the nonstandard 
prefix "/opt/subversion" might mean that I need to alter the PYTHONPATH 
environment variable; but adding "/opt/subversion/lib" to this variable 
didn't seem to help the situation.

Can someone shed some insight into why python is unable to see these 
bindings?

Thanks in advance!
