Hi all,

I gave this a dime of my time and figured that you'd get a
similar problem with two (or more) repositories that cross
reference each other using svn:external. The only possible
solution I can see would be for the client checkout code to
handle this (if at all possible).

P.s. Dave, I'm sorry for the double posting.
