configureにroot権限が必要とかふざけているんじゃないの？

vpopmailのインストール

./configure --enable-roaming-users --disable-clear-passwd
 --enable-relay-clear-minutes=10 --enable-tcpserver-file=/home/vpopmail/etc/tcp.smtp
 --enable-logging=y

configure: WARNING: === vpopmail must be configured as root. ===
configure: WARNING: === please switch to the root user and  ===
configure: WARNING: === run ./configure. Thanks ===
configure: error: aborted.

な、なにこれ。
