st: constrained tobit regression?

Dear all,
I'm trying to run a tobit regression with a constraint. The ususal way to run a tobit regression is:
tobit var1 var 2 var 3 var4..., ll(0)
Is there a way to run a tobit regression with a constraint? In particular, I intend to incorporate a linear constraint that requires that some of the coefficients sum up to zero, e.g.,
constraint 1 var2 + var3 = 0
The command
tobit var1 var 2 var 3 var4..., ll(0), constraint(1)
does not work.
Best
Matthias
