I am not doing any redirection on the local server, and this occurs if
I go to the local server directly, so has nothing to do with
redirection.

The server isn't using me as the user, but yes, all the public_html
stuff is world readable.

Sorry, what I mean is I tried making the "unreadable" files (as
reported by error.log) readable by putting them in the "www-data"
group which apache2 uses on Ubuntu.

Ah, thanks, good tip.  This will help.  However, for some reason this
and other pages are not currently available for some reason.

Because I could not push to the shared server anyway, or secure it
properly, so the best thing for me to do (now that I'm using linux)
was to just use my actual working copy locally.

No, this is exactly why I didn't do this... because when I put:

/home/patrick/hg/cbl-dev = /home/patrick/hg/cbl-dev

as that directory is outside the public_html directory root, it cannot
be served.

I'm using hgwebdir.cgi, but have renamed it to index.cgi for convienence.
Currently, it has this:

application = hgwebdir('hgweb.config')

so I'm not sure at all what replacing or adding the above would do.
I'll have to get out my CGI book I guess.
