Oh yes! i didn't notice it because i always do su before i compile ports.
But if i try to compile port not being root i get:

$ make
===>  Switching to root credentials to create /var/db/ports/mc
Password:
===>  Returning to user credentials
[1] + Stopped (tty output)    make
$

I guess this happens to ANY port which is smart enough to switch to root before
building.

My shell is /bin/sh
FreebSD 7-PRERELEASE
