SubVersion on Mac OS X

I’ve written a WP plugin, and now I’m trying to upload it to https://svn.wp-plugins.org/mypixs/ , but I have no idea how to do this.

I should need to install some sort of application (SubVersion) so I can access the svn folder via the Terminal (Mac OS X Tiger), so I Googled a little bit and installed this application : https://downloads.open.collab.net/binaries.html

Everything was installed correctly (at least, that’s what the installer said), but the Terminal doesn’t recognize the “svn” command…

Does anyone know how this can be solved?
