set path for package

I tried to used to package a brew one to distribute to other mac. 

When I do  brew pkg --with-deps --identifier-prefix org.pass pass
==> Creating package staging root using Homebrew prefix /Users/USER/usr/local

Because my brew is installed on /Users/USER. 

How to fix this ? How can I set the install path so the other machines will installed in their /Users/USER2 prefix ?
