svn on OSX 10.7.3 can't find CA certificates

Hi. I'm having some trouble with command-line svn on OSX 10.7.3 . The problem appears to be that subversion can't find the CA certificates that are installed on my system (visible in Keychain Access.) I get the following error:

$ svn log
Error validating server certificate for 'https://<repo>:443':
 - The certificate is not issued by a trusted authority. Use the
   fingerprint to validate the certificate manually!
Certificate information:
 - Hostname: *.<repo>
 - Valid: from Sun, 12 Feb 2012 02:34:03 GMT until Mon, 15 Apr 2013 19:02:56 GMT
 - Issuer: GeoTrust, Inc., US
 - Fingerprint: <stuff>

As you can see, the dates are OK, and the CA is valid. Going to the same url in Safari and Firefox gives a valid SSL connection.

Does anyone have any suggestions?
