Install user defaulting to "current" user

This doesn't make sense to me, it seems the default now is to install things as "user"."user":

/usr/bin/install -c -d -o leif -g leif /usr/local/var/trafficserver /usr/local/var/log/trafficserver /usr/local/etc/trafficserver /usr/local/etc/trafficserver/internal
/usr/bin/install: invalid group `leif'

I thought our default was nobody.nobody, and this was supposed to be overridable via ./configure options? Also, with the trunk, records.config gets

CONFIG proxy.config.admin.user_id STRING leif

which I don't think makes sense either.
