problen with pw useradd?

[Bernt Hansson]

Hello list!

I have a strange problem when trying to install dns/rbldnsd.

Problem is that there is no user rbldns trying to pw useradd there is a 
user called rbldns.

Well here it is;

===> Creating users and/or groups.
Using existing group 'rbldns'.
Creating user 'rbldns' with uid '153'
pw: user 'rbldns' already exists.
pkg-static: PRE-INSTALL script failed
pkg-static: unknown user 'rbldns'
....

pw useradd rbldns
pw: user'rbldns' already exists.
