Post-Commit Hook

I am creating a post-commit hook. The intent is to do an svn update in
the post-commit hook. I've got the post-commit working to do the email
in this line:

REPOS="$1"

REV="$2"

/usr/home/svn/commit-email.pl "$REPOS" "$REV" -r me@mydomain.com
me@mydomain.com

The above code is working lovely. As soon as I add this line, the
post-commit hook bombs:

/usr/local/bin/svn update
/usr/home/httpd/domains/www.carroll.edu/siteprod

If I "su svn" on the server and try to run that command in command line,
I get the following message:

svn: Can't open file
'/usr/home/httpd/domains/www.carroll.edu/siteprod/.svn/lock': Permission
denied

I also recursively chown'd my directory to change the ownership of the
repo files' owner to svn.

Still not working. Any help?
