[Pharo-project] SmallLint broken -- no literalsDo: in CompiledMethod ?

Hi, I was trying out the refactoring engine, and tried to run the code critic. I got a message not understood in SmalllintContext>>addLiteralsFor: which sends literalsDo: to its argument aCompiledMethod. This appears to be the only method in the Pharo-dev image that sends this msg. Any ida what the fix should be? - on
