If you're using Apache 2 (with the new easyapache), then you could try compiling subversion from source - I did this and it adds the relevant modules to /usr/local/apache/modules/ as well as httpd.conf.
The only problem I have now is:
Code:
Internal error: Can't open file '/path/to/subversion/404.shtml/format': No such file or directory
I can access the repositories fine within my browser - it just doesn't work from the subversion client.
If you need any help getting it installed and running, I can probably help, but until I can fix the error above, I'm stuck too!
