mail/mailman package bug?

[Fredrik Pettai <pettai%nordu.net@localhost>]

Hi,

I get this error while installing mail/mailman from pkgsrc-2009Q2 (and  
-current) on both NetBSD/i386 4.0.1 and NetBSD/amd64 5.0_STABLE:

=> Running POST-INSTALL script actions

I guess it's a consequence of that the mailman UID doesn't get  
installed during "make install" (earlier from the installation output):

=> Running PRE-INSTALL script actions
mailman-2.1.12: Creating group ``mailman''
mailman-2.1.12: Creating user ``mailman''
useradd: Warning: home directory `/nonexistent' doesn't exist, and -m  
was not specified

Is there someone else that has seen this problem? I have a weak memory  
of some other package failing just like this with a /nonexistent  
homedir creation, but googling around make me think that it pre-dates  
pkgsrc-2007Qx).
