I don't believe you can join two regex's together using string concatenation. If you spell it out, it works: 
$teststring =~ s/hello\s*$RE{balanced}{-parens=>'{ }'}\s*$RE{balanced}
+{-parens=>'{ }'}/hi/;
#teststring: start hi end

(Except you didn't have any capture parentheses in your original s///.)

Unless I state otherwise, all my code runs with strict and warnings
