>Description:
After compiling vnstat, the installation process dies on the section
"Creating users and/or groups."

A group 'vnstat' is created.  A user is then created, but the installation thinks that vnstat user disappeared in the process, so it bombs.  Subsequent runs die on user creation - perhaps it should reuse existing created user.

--output follows--
===> Creating users and/or groups.
Creating group `vnstat' with gid `284'.
Creating user `vnstat' with uid `284'.
pw: user 'vnstat' disappeared during update
*** [create-users-groups] Error code 67

Stop in /usr/ports/net/vnstat.
*** [install] Error code 1

Stop in /usr/ports/net/vnstat.



$ make install

===> Creating users and/or groups.
Using existing group `vnstat'.
Creating user `vnstat' with uid `284'.
pw: user 'vnstat' already exists
*** [create-users-groups] Error code 74

Stop in /usr/ports/net/vnstat.
*** [install] Error code 1

Stop in /usr/ports/net/vnstat.

>How-To-Repeat:
cd /usr/ports/net/vnstat
make install clean
(don't select any options)
..wait for crash

make install
..crash with a different output this time
>Fix:
First instance of creating user should not think the user disappeared in the process.  Subsequent runs should find duplicate user and re-use its ID instead of just dying.
