Redmine

Hey, I'm running redmine on webrick (I plan on changing it soon) on top of archlinux with a postgresql database using ruby 1.8.7 and rails 2.1.2. The svn repo is a separate centos box using http and https (Redmine runs on another box because centos doesn't officialy have rubygems, and the repo is too sensitive to run it on arch)

For some reason I can't see the svn repo, how could I know the error svn throws? I'm not a rails or even ruby programmer, but I do know how to program, I'd be really grateful if you told me how to do it so I can fix my servers.
