the metric numberOfLinesOfCode it doesn't work on an imported moose smalltalk model because it looks for the compiled method version to calculate the actual lines of code. I think we should seriously rethink the entire smalltalk importing and handling phase because it is not possible that only pharo can be imported and analyze: In all the places where a "isSmalltalk" method is invoked, if that means that you are going to look for smalltalk code in the image, we should change it with a method called "isSmalltalkCodeLoaded". This method can be set since the import phase.

PS: I hope I can make the code I wrote to import Smalltalk available ASAP, that could be use as a start to create a image code independent parser/importer :)
