You need to write your own program therefore, say as here:
sysuse auto, clear
program myprog, rclass
version 9
syntax varlist(min=2 max=2 numeric) [if] [in]
tokenize "`varlist'"
args v1 v2
su `v1' `if' `in', meanonly
return scalar mean1 = r(mean)
su `v2' `if' `in', meanonly
return scalar mean2 = r(mean)
end
bootstrap mean1=r(mean1) mean2 = r(mean2) : myprog turn trunk
