Sorry! I was going to respond yesterday, but I got distracted by other 
things.

Did you use the exact URL scheme described there or something slightly 
different? What worries me with these instructions is the use of things 
like ScriptAliasMatch, which is more complicated than ScriptAlias and 
has some pitfalls, along with things like mixing up the repository 
location with the Web publishing directory (albeit the CGI directory). 
This can lead to debugging problems later.

See 
http://mercurial.selenic.com/wiki/PublishingRepositories#Publishing_multiple_repositories 
for some details of the configuration file, although I see that 
wildcards are not described there, so maybe some notes there are also 
required. Nevertheless, your configuration seems reasonable, and you 
shouldn't bother making symbolic links into /var/www/cgi-hg, which is 
what the RHEL4 page suggests.

Does it list "projecta" in the hgweb user interface or as an Apache 
directory listing?

This indicates that the template serving the page doesn't find 
sessionvars, which would suggest that the hgweb repository template is 
being asked to serve up the hgweb repository *list*. Or that's one 
possible explanation.

Do you have symbolic links to the repositories in the CGI directory? If 
so, remove them. That will remove one source of confusion about what 
Apache will be attempting to do with your repositories.

P.S. Don't worry: we'll figure this out eventually; it just takes some 
patience.
