Constructor not defined: [selectOption].<Constructor>(String, String)

The following code in other people's development environment is right,but   in my development environment is wrong.Why?

 

  public List<SelectOption> getItems() {
          List<SelectOption> options = new List<SelectOption>();
          options.add(new SelectOption('US','US'));
          options.add(new SelectOption('CANADA','Canada'));
          options.add(new SelectOption('MEXICO','Mexico'));
          return options;
   }

 error:Constructor not defined: [selectOption].<Constructor>(String, String)

 

  

in addition:

  PageReference acctPage = new ApexPages.StandardController(account).view();

error:Illegal assignment from System.PageReference to pageReference

 

what is the difference between  System.PageReference  and pageReference?
