403 Forbidden! can't find index! HELP

I am installing rails on a hosting server (aplus.net) where I have
very limited access (no root access, I'm limited to my /home/
usernames/ dir). They had ruby installed but no rubygems or rails.

I got rubygems and rails up and running, I created a new app in
www.mydomain.com/testruby, but when I go there I get a 403 - Forbidden
error:

"Forbidden
You don't have permission to access /testruby/ on this server.
You may need to create an index.html page or enable the directory
browsing by creating an .htaccess file containing "Options +Indexes"."

The aplus.net server seems to be running:
Apache 1.3.36
CGI 3.10

I checked my CHMOD permissions on the dir and they seem to be set
correctly.

Man, I felt like I was so close to getting this running I could taste
it!

I'm new to this server stuff, could someone please help me?

Hey James,

Did you get any further on this? I am stuck trying to install rails:

gem install rails --include-dependencies
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
    Permission denied - connect(2)(Errno::EACCES)

I am on aplus as well. I am hosting my other clients apps on planet
argon and it works nicely.

Thanks,

Scott
