Subversion has a single, global revision number. Just ask for that number
and use it for your build. For example:

rev="`svn stat -u README | awk '/^Head/ { print $3 }'`"
svn up -r $rev

Depending on your setup, you might also do that last step as:

svn co REPOS_URL -r $rev -d build-tmp

The basic point is, that you can ask for the head revision, then update or
checkout a working copy for that revision. There isn't a need to create
labels or anything.
