[SDL] I can't seem to get source using SVN - anything wrong?

[Doug]

I was interested in taking a look at the current 1.3 SDL sources in SVN.

I issued the command, "svn checkout svn://libsdl.org/trunk/SDL"

But I get this error message, "svn: Can't connect to host 'libsdl.org': 
No connection could be made because the target machine actively refused 
it."

I tried another SVN repository (not SDL) and it's working fine.  Is SVN 
access (even just read-only) to SDL currently not available?

Thanks,
Doug.
