Right, the "-r" is being picked up as if it was a parameter to "svn
propset" as opposed to an attribute of the external. Have you
considered specifying the revision via a peg revision instead? This
uses a slightly different syntax but will likely yield the same results
for you:
svn propset svn:externals "^/../framework/trunk/database_at_661 database" .
