[Moin-user] problem installing moin as standalone on gentoo

[dave s]

Hi all,

I got my standalone server working on ubnutu by downloading the package 
from the moin website, un tarring it etc and following ...

http://moinmoin.wikiwikiweb.de/HelpOnInstalling/WikiInstanceCreation

it worked a treat.

I now need to do the following on my gentoo box, I did the same but got 
the following problem ...

dave_comp moin # ls -al
total 32
drwxr-xr-x    8 root root 4096 Oct 16 16:31 .
drwxr-xr-x  187 root root 4096 Sep 18 13:46 ..

chown: `www-data.www-data' syntax is obsolete; use `:' since this will 
be removed in the future
chown: `www-data.www-data': invalid user

OK I am stuck, can anyone help me ?

Cheers
Dave

PS I am using the package from the moin website because all I want is a 
standalone server, I am not confident in setting up apache securely :)
