[Koha] Is this a problem?

[Paul Yachnes]

At the very end of a Koha install (git install on Ubuntu 9.04), I got
the following text:

chown:  invalid user:  'koha:koha'
make:  *** [set_koha_ownsership] Error 1

I'm not sure what this is telling me or if this is a problem. Do I need
to fix something or is it ok to proceed?
