Yes. 

1. In general terms, you cannot run Stata 7 programs
under Stata 6, or programs written for version n on 
any previous version < n. 

2. Sometimes the version number is cosmetic 
and could be changed down with no effect. 
In fact, Lee's program  makes much use 
of various constructs used in Stata 7. It 
could, in principle, be back-translated to Stata 6.
You could try that yourself, or someone might 
volunteer. 

3. Generally again, many user-programmers 
find that it is to their advantage 
to exploit the features of the latest 
Stata and make their programs available 
on the basis "If this is usable and useful to 
you, that's fine by me". Some put effort 
in maintaining versions which will run 
on earlier Statas: Roger Newson is 
one example.
