All of the routines in my 'panelauto' package require that you  
provide a single panel. Thus

webuse grunfeld
reg invest L.invest time
durbina2

reports an error, since more than one panel (company) enters the  
regression. But if you reg ... if company==1 you may then use  
durbina2.  Official Stata 7's durbina will not work in that context.  
But Durbin's alternative test (like the D-W) is not made to test for  
AR(1) in multiple time series, so your regression below cannot be  
followed by a Durbin test of any flavor.
