You have an old version:

. which whitetst
*! whitetst 1.2.3 CFB/NJC  17 Feb 2002 add fitted option for special 
form of test

According to the help,

"Alternatively, a special form of the test, described by Wooldridge 
(2000, pp. 259-260), may be employed by specifying the fitted option. 
In this form, the predicted values from the original regression and 
their squares are used in place of the individual regressors, their 
squares, and
their cross-products. This form of the test imposes constraints on 
the auxiliary regression, but may be a very attractive alternative if 
the original regressor list is lengthy."
