I am not volunteering to write an expect script for you though it could be
done with either expect or p5-Expect-Simple. Expect scripts, if reliable,
are very difficult to write and mistakes can, in many cases, be disastrous.
I had to write and support scripts to talk to network routers and switches
and I can't recommend it. There is always some possible response that you
either didn't know about or thought you would never receive that blows
things out of the water. And screen scraping is always risky as a minor
change between versions can break everything.

I am concerned with why this is happening. I have run "svn up /user/ports"
nightly for years with no issues like you describe. This simply should not
be happening. I'm curious as to why.

Are you running svn in a script or manually? What command are you using?
What version of subversion is installed or are you running the base
svnlite? (I use the full-blown subversion.)
Are you manually doing any edits to the ports tree?
Have you looked at the output of "svn status /usr/ports"?
