[mail/qmail] make install fails on existing /var/qmail/.qmail-postmaster files

[Spil Oss]

snippet from make install

install  -o root -g wheel -m 555
/usr/ports/mail/qmail/work/enable-qmail /var/qmail/scripts
touch: /var/qmail/alias/.qmail-mailer-daemon: No such file or directory
Failed to create files :
  /var/qmail/alias/.qmail-postmaster
  /var/qmail/alias/.qmail-root

after `mv  var/qmail/alias /var/qmail/alias~`
make install ran fine

possibly due to missing .qmail-mailer-daemon file but existing other files?

Greets,
