Can you explain a little a mor eabotu what you are trying to
accomplish, and where you are at thus far?
-Are you trying to set-up an SVN server and repository for managing
and versioning the rails application you are creating?
-Are you trying to set-up and SVN client so you can checkout/install
plugins, etc from SVN repositories into your rails application?
-What OS are your on OSX, Windows, or Linus/Unix?
-Are you using an IDE such as Aptanta?
Some general thoughts/tips:
