Redmine

Hello all and thank you for Redmine it just rocks!

Here is my problem:
I have installed Redmine in shared host (DashingHost) with success and i am using it with a redirect in subdomain pojects.mydomain.net,
the problem is that i could not follow the steps from "HowTo configure Redmine for advanced Subversion integration" in HowTos section.
I tried the steps from the guide but as i don't have administrator access to the system i cannot implement it. Right now all i can do is to create a repository and then add it to the Redmine project.

Is there an alternative way to do this without having administrator's access to the server?
I have a restricted ssh access to the server if that helps.
Subversion in the system was installed with cPanel' Rvskin all together with Trac.

Thank you in advance,
Stef
