            Not sure how reliable the presence of this 'compilation.problem' file is ... 
                     I just noticed it in recent PDE builds with compile problems. 
                     May have to make this "fancier" in future. 
                     For now, looks only one level down in plugins directory (in build's workdir) for a file with 
                     the name 'complilation.problem'. We may have a "summary" in xml file format, summarizing logs, 
                      ... but not sure then created (during site? We'd have to call site first. This way, we'll see if the match :) .
