That looks like old syntax (even for Stata 9). The following 
works on my version of Stata 9(*):

*---------------- begin example -------------------------
sysuse auto, clear
preserve
keep if !missing(rep78)
bootstrap mean=r(mean), reps(100) : summ rep78, meanonly
restore 
*----------------- end example --------------------------
(For more on examples I sent to the Statalist see: 
http://www.maartenbuis.nl/example_faq )

Hope this helps,
Maarten

(*) For those that wonder why I have Stata 9 on my computer:
I use it to run certification scripts of my programs that I
claim should work under Stata 9
